ASoC: codecs: ES8326: regcache_sync error issue

Browse Source 
We modified the regmap_config members to fix cach sync error.
There are several registers that should be read-only registers.
If these registers are written while synchronizing the register values,
the codec will enter an error state.So we create es8326_writeable_register,
and set these registers to false
