Peter Ujfalusi 63c3194b82 ASoC: tlv320aic3x: Mark the RESET register as volatile 
The RESET register only have one self clearing bit and it should not be
cached. If it is cached, when we sync the registers back to the chip we
will initiate a software reset as well, which is not desirable.

* ALSA SoC TLV320AIC3X codec driver

*
* Notes:
* The AIC3X is a driver for a low power stereo audio
* codecs aic31, aic32, aic33, aic3007.
*
* It supports full aic33 codec functionality.
* The compatibility with aic32, aic31 and aic3007 is as follows:
* aic32/aic3007 | aic31
* ---------------------------------------
* MONO_LOUT -> N/A | MONO_LOUT -> N/A
* | IN1L -> LINE1L
* | IN1R -> LINE1R
* | IN2L -> LINE2L
* | IN2R -> LINE2R
* | MIC3L/R -> N/A
* truncated internal functionality in
* accordance with documentation
* ---------------------------------------
*
* Hence the machine layer should disable unsupported inputs/outputs by
* snd_soc_dapm_disable_pin(codec, "MONO_LOUT"), etc.
