ARM: SoC cleanups

This is a good healthy set of various code removals. Total net delta is 8100
 lines removed.
 
 Among the larger cleanups are:
 
 - Removal of old Samsung S3C DMA infrastructure by Arnd
 - Removal of the non-DT version of the 'lager' board by Magnus Damm
 - General stale code removal on OMAP and Davinci by Rickard Strandqvist
 - Removal of non-DT support on am3517 platforms by Tony Lindgren
 
 ... plus several other cleanups of various platforms across the board.

ARM Atmel SoCs (aka AT91)
=========================
Introduction
------------
This document gives useful information about the ARM Atmel SoCs that are
currently supported in Linux Mainline (you know, the one on kernel.org).
It is important to note that the Atmel | SMART ARM-based MPU product line is
historically named "AT91" or "at91" throughout the Linux kernel development
process even if this product prefix has completely disappeared from the
official Atmel product name. Anyway, files, directories, git trees,
git branches/tags and email subject always contain this "at91" sub-string.
AT91 SoCs

Documentation and detailled datasheet for each product are available on
the Atmel website: http://www.atmel.com.

Linux kernel information
------------------------
Linux kernel mach directory: arch/arm/mach-at91
MAINTAINERS entry is: "ARM/ATMEL AT91RM9200 AND AT91SAM ARM ARCHITECTURES"
Device Tree for AT91 SoCs and boards
------------------------------------
All AT91 SoCs are converted to Device Tree. Since Linux 3.19, these products
must use this method to boot the Linux kernel.
Work In Progress statement:
Device Tree files and Device Tree bindings that apply to AT91 SoCs and boards are
considered as "Unstable". To be completely clear, any at91 binding can change at
any time. So, be sure to use a Device Tree Binary and a Kernel Image generated from
the same source tree.
Please refer to the Documentation/devicetree/bindings/ABI.txt file for a
definition of a "Stable" binding/ABI.
This statement will be removed by AT91 MAINTAINERS when appropriate.
Naming conventions and best practice:
- SoCs Device Tree Source Include files are named after the official name of
the product (at91sam9g20.dtsi or sama5d33.dtsi for instance).
- Device Tree Source Include files (.dtsi) are used to collect common nodes that can be
shared across SoCs or boards (sama5d3.dtsi or at91sam9x5cm.dtsi for instance).
When collecting nodes for a particular peripheral or topic, the identifier have to
be placed at the end of the file name, separated with a "_" (at91sam9x5_can.dtsi
or sama5d3_gmac.dtsi for example).
- board Device Tree Source files (.dts) are prefixed by the string "at91-" so
that they can be identified easily. Note that some files are historical exceptions
to this rule (sama5d3[13456]ek.dts, usb_a9g20.dts or animeo_ip.dts for example).

S3C2410 DMA
===========
Introduction
------------
The kernel provides an interface to manage DMA transfers
using the DMA channels in the CPU, so that the central
duty of managing channel mappings, and programming the
channel generators is in one place.
DMA Channel Ordering
--------------------
Many of the range do not have connections for the DMA
channels to all sources, which means that some devices
have a restricted number of channels that can be used.
To allow flexibility for each CPU type and board, the
DMA code can be given a DMA ordering structure which
allows the order of channel search to be specified, as
well as allowing the prohibition of certain claims.
struct s3c24xx_dma_order has a list of channels, and
each channel within has a slot for a list of DMA
channel numbers. The slots are searched in order for
the presence of a DMA channel number with DMA_CH_VALID
or-ed in.
If the order has the flag DMA_CH_NEVER set, then after
checking the channel list, the system will return no
found channel, thus denying the request.
A board support file can call s3c24xx_dma_order_set()
to register a complete ordering set. The routine will
copy the data, so the original can be discarded with
__initdata.

*
* omap_pm_set_min_clk_rate() differs from the clock code's
* clk_set_rate() in that it considers other constraints before taking
* any hardware action, and may change a system OPP rather than just a
* clock rate. clk_set_rate() is intended to be a low-level
* interface.
*
* omap_pm_set_min_clk_rate() is easily open to abuse. A better API
* would be something like "omap_pm_set_min_dev_performance()";
* however, there is no easily-generalizable concept of performance
* that applies to all devices. Only a device (and possibly the
* device subsystem) has both the subsystem-specific knowledge, and
* the hardware IP block-specific knowledge, to translate a constraint
* on "touchscreen sampling accuracy" or "number of pixels or polygons
* rendered per second" to a clock rate. This translation can be
* dependent on the hardware IP block's revision, or firmware version,
* and the driver is the only code on the system that has this
* information and can know how to translate that into a clock rate.
*
* The intended use-case for this function is for userspace or other
* kernel code to communicate a particular performance requirement to
* a subsystem; then for the subsystem to communicate that requirement
* to something that is meaningful to the device driver; then for the
* device driver to convert that requirement to a clock rate, and to
* then call omap_pm_set_min_clk_rate().
*
* Users of this function (such as device drivers) should not simply
* call this function with some high clock rate to ensure "high
* performance." Rather, the device driver should take a performance
* constraint from its subsystem, such as "render at least X polygons
* per second," and use some formula or table to convert that into a
* clock rate constraint given the hardware type and hardware
* revision. Device drivers or subsystems should not assume that they
* know how to make a power/performance tradeoff - some device use
* cases may tolerate a lower-fidelity device function for lower power
* consumption; others may demand a higher-fidelity device function,
* no matter what the power consumption.
*
* Multiple calls to omap_pm_set_min_clk_rate() will replace the
* previous rate value for the device @dev. To remove the minimum clock
