ASoC: wm8731: Drop wm8731_writeable function

Browse Source 
When .max_register is set and .writeable_reg is not implement, registers
between 0 and .max_register are writeable. This is the same as current
implementation of wm8731_writeable(), so just drop implementation for
.writeable_reg callback.
