ASoC: fsl_sai: Add missing registers to cache default

Browse Source 
[ Upstream commit 90ed688792a6b7012b3e8a2f858bc3fe7454d0eb ]

Drivers does cache sync during runtime resume, setting all writable
registers. Not all writable registers are set in cache default, resulting
in the erorr message:
  fsl-sai 30c30000.sai: using zero-initialized flat cache, this may cause
  unexpected behavior

Fix this by adding missing writable register defaults.
