Dmitry Lavnikevich 31d9f8faf9 ASoC: tlv320aic3x: fix PLL D configuration
Current caching implementation during regcache_sync() call bypasses
all register writes of values that are already known as default
(regmap reg_defaults). Same time in TLV320AIC3x codecs register 5
(AIC3X_PLL_PROGC_REG) write should be immediately followed by register
6 write (AIC3X_PLL_PROGD_REG) even if it was not changed. Otherwise
both registers will not be written.

This brings to issue that appears particulary in case of 44.1kHz
playback with 19.2MHz master clock. In this case AIC3X_PLL_PROGC_REG
is 0x6e while AIC3X_PLL_PROGD_REG is 0x0 (same as register
default). Thus AIC3X_PLL_PROGC_REG also remains not written and we get
wrong playback speed.

In this patch snd_soc_read() is used to get cached pll values and
snd_soc_write() (unlike regcache_sync() this function doesn't bypasses
hardware default values) to write them to registers.
