ASoC: codecs: wcd934x: Fix slimbus overflow

Browse Source 
Remove MCLK_CONTROL and FS_CNT_CONTROL from
the list of volatile registers so that regmap
sync happens for these registers when coming
out of power collapse. These clock registers
need to be synced otherwise codec state is not
restored correctly after power collapse.
