[PATCH 1/1] ASoC: mediatek: mt8188: add register to volatile_register

[yr . yang]

From: YR Yang <yr.yang@xxxxxxxxxxxx>

Add AFE Control Register 0 to volatile_register.
AFE_DAC_CON0 can be modified by both SOF and ALSA driver.
If this register read & write by cache mode, 
the cached value may be not the real value
when the register modified by other side.
It will cause playback or capture fail.
Need add AFE_DAC_CON0 to volatile register.
