This patch adds support for the Cirrus Logic CS42448/CS42888 Audio CODEC that
has six/four 24-bit AD and eight 24-bit DA converters.

[ CS42448/CS42888 supports both I2C and SPI control ports. As initial patch,
  this patch only adds the support for I2C. ]

There was a overlap between the snd_soc_codec_set_cache_io() cleanup and the
addition of the sirf-audio-codec resulting in the sirf-audio-codec driver still
using the old signature of snd_soc_codec_set_cache_io(), which will cause a
compile error. Since the core is able to automatically setup IO for this driver
we can just remove both the snd_soc_set_cache_io() call and the control_data
assignment.

This commit adds a bare bones driver support for TLV320AIC31XX family
audio codecs. The driver adds basic stereo playback trough headphone
and speaker outputs and mono capture trough microphone inputs.

The driver is currently missing support at least for mini DSP features
and jack detection. I have tested the driver only on TLV320AIC3111,
but based on the data sheets TLV320AIC3100, TLV320AIC3110, and
TLV320AIC3120 should work Ok too.

The base for the implementation was taken from:
git@gitorious.org:ti-codecs/ti-codecs.git ajitk/topics/k3.10.1-aic31xx
-branch at commit 77504eba0294764e9e63b4a0c696b44db187cd13.

regmap should handle any byte ordering issues required, it is looking for
a byte stream from the bus, so don't set 16 bits per word. This is likely
to have tested out OK due to use of an unmerged SPI controller driver.

Now that all users have been converted to regmap and the config.reg_bits
and config.val_bits can be setted by each user through regmap core API.
So these two params are redundant here.

Since the only control type that left is SND_SOC_REGMAP, so remove it. Drop
the control params and add struct regmap *regmap to simplify the code.

Currently the FLL configuration is calculated before it is known which
FLL path the configuration will be applied to. Newer versions of the IP
have differences in the configuration required for each FLL path, which
makes it complicated to calculate the FLL configuration in advance.

This patch simply checks the validity of a requested input and output
frequency before we know which FLL path they will be applied to and
saves the actual calculation of the configuration until we know where
the settings will be applied.

Pre-merge code was using direct hw_read() calls as an out of framework
way of doing volatile register I/O when not using regmap. This has never
functioned correctly in mainline due to the regmap conversion, the
hw_read() implementation still does caching. In order to facilitate
removal of the subsystem level I/O code convert to use snd_soc_read(),
there should be no functional impact.

The wm8763 driver uses regmap for IO which means that codec->cache_sync is not
used. The line was added in commit d3398ff0 ('ASoC: Convert WM8753 to direct
regmap API usage'). Presumably this was meant to be regcache_mark_dirty(), but
since we already call regcache_mark_dirty() in the core when suspending the
CODEC it is safe to just remove the line.
