The mailbox module is capable of generating two interrupts
to MPU in OMAP2420, compared to one in OMAP2430. The second
interrupt is to handle interrupts from the additional IVA
processor present only on OMAP2420.
Move the current common mailbox DT node into the SoC
specific files to allow the above differentiation. Also,
added back the interrupt-names on OMAP2420, that were
previously defined in hwmod data.
This fixes regression caused by the recent dropping of
hwmod data in favor for defining it in the .dts files.

Add DT data for OMAP2 display subsystem, which contains the following
blocks:
dss - the wrapper/glue for the display modules
dispc - display controller
rfbi - MIPI DBI encoder
venc - analog TV encoder

The irq data for rng module defined in hwmod data previously
missed the OMAP_INTC_START relative offset, so the interrupt
number is probably misconfigured during the DT node addition
adjusting for this OMAP_INTC_START. Interrupt #36 is associated
with a watchdog timer, so fix the rng module's interrupt to the
appropriate interrupt #52.

Looks like we're missing few entries for omap2 and the drivers
have only worked because of the omap hwmod building the devices
for the missing entries.
Let's fix the missing entries so we don't need to rely on hwmod
for the basic data and can then later on remove the duplicate
data from hwmod. Otherwise device tree only drivers will not
work properly.

Update the DMTIMER compatibility property to reflect the register level
compatibilty between devices and update the various OMAP/AM timer
bindings with the appropriate compatibility string.
By doing this we can add platform specific data applicable to specific
timer versions to the driver. For example, errata flags can be populated
for the timer versions that are impacted.

Add PMU nodes for OMAP2, OMAP3 and OMAP4460 devices.
Please note that the node for OMAP4460 has been placed in a separate
header file for OMAP4460, because the node is not compatible with
OMAP4430. The node for OMAP4430 is not included because PMU is not
currently supported on OMAP4430 due to the absence of a cross-trigger
interface driver.

Add the 12 GP timers nodes present in OMAP3.
Add the 11 GP timers nodes present in OMAP4.
Add the 7 GP timers nodes present in AM33xx.
Add documentation for timer properties specific to OMAP.
Thanks to Vaibhav Hiremath for creating the AM33xx timer nodes. I have modified
Vaibhav's original nodes adding information on which timers support a PWM
output.
V5 changes:
- Updated timer register sizes for OMAP2/3/4.
- Modified AM335x timer register size to be 1KB instead of 4KB to align with
HWMOD.

The interrupt-parent attribute does not have to be added in each
node since the fmwk will check for the parent as well to get it.
Create an interrupt-parent for OMAP2, OMAP3, AM33xx and remove the
attributes from every nodes that were using it.
