snd_soc_card_jack_new() allowed to create jack kcontrol without pins,
but did not create kcontrols. The jack would not have kcontrols if pins
were not going to be added.
This renames the old snd_soc_card_jack_new() to
snd_soc_card_jack_new_pins() for use when pins are provided or will be
added later. The new snd_soc_card_jack_new() appropriately creates a
jack for use without pins and adds a kcontrol.

Add AHUB routes for ASRC module. The ASRC module can be plugged into audio
path as per the need. The routing controls can be used to setup the audio
path with ASRC similar to the already existing routes. The routes are added
to Tegra186 and later Tegra SoCs where ASRC module is present.

Asynchronous Sample Rate Converter (ASRC) converts the sampling frequency
of the input signal from one frequency to another. It can handle over a
wide range of sample rate ratios (freq_in/freq_out) from 1:24 to 24:1.
ASRC has two modes of operation. One where ratio can be programmed in SW
and the other where it gets the information from ratio estimator module.
The latter mode above can help address the cases where the sample rate is
not known at the stream set up time or is potentially time varying.
In addition, the ratio between input and output sample rate can be any
arbitrary number and the input and output clocks could be derived from
asynchronous clocks.
This patch registers ASRC driver with ASoC framework. The component driver
exposes DAPM widgets, routes and kcontrols for the device. The DAI driver
exposes ASRC interfaces, which can be used to connect different components
in the ASoC layer. Makefile and Kconfig support is added to allow build
the driver.

Support new nvidia,fixed-parent-rate device-tree property which instructs
I2S that board wants parent clock rate to stay at a fixed rate. This allows
to play audio over S/PDIF and I2S simultaneously. The root of the problem
is that audio components on Tegra share the same audio PLL, and thus, only
a subset of rates can be supported if we want to play audio simultaneously.
Filter out audio rates that don't match parent clock rate if device-tree
has the nvidia,fixed-parent-rate property.

SPDIF and other SoC components share audio PLL on Tegra, thus only one
component may set the desired base clock rate. This creates problem for
HDMI audio because it uses SPDIF and audio may not work if SPDIF's clock
doesn't exactly match standard audio rate since some receivers may reject
audio in that case. Filter out audio rates which SPDIF output can't
support, assuming that other components won't change rate at runtime.

- Clean up whitespaces, defines and variables.
- Remove obsolete code.
- Adhere to upstream coding style.
- Don't override returned error code.
- Replace pr_err with dev_err.
No functional changes are made by this patch. This is a minor code's
refactoring that will ease further maintenance of the driver.

The DMA resource is never set up anywhere, and passing this as slave_id
has not been the proper procedure in a long time.
As a preparation for removing all slave_id references from the ALSA code,
remove this one.
According to Dmitry Osipenko, this driver has never been used and
the mechanism for configuring DMA would not work as it is implemented,
so this part will get rewritten when the driver gets put into use
again in the future.

The MVC module has a per channel control bit, based on which it decides
to apply channel specific volume/mute settings. When per channel control
bit is enabled (which is the default HW configuration), all MVC channel
volume/mute can be independently controlled. If the control is disabled,
channel-0 volume/mute setting is applied by HW to all remaining channels.
Thus add support to leverage this HW feature by exposing master controls
for volume/mute.
With this, now there are per channel and master volume/mute controls.
Users need to just use controls which are suitable for their applications.
The per channel control enable/disable is mananged in driver and hidden
from users, so that they need to just worry about respective volume/mute
controls.
