ASoC: cs35l56: Add Mute, Volume and Posture registers to firmware register list

Registers to set Mute, Volume and Posture are inside firmware,
which means they should be added to the list of registers set inside
firmware, in case they vary across Device or Revision.

These three registers are also used for controls, so additional
handling is required to be able to obtain and set the register inside
ALSA controls.
