ASoC: SDCA: Force some SDCA Controls to be volatile
Whilst SDCA does specify an Access Mode for each Control, there is not a
1-to-1 mapping between that and ASoC's internal representation. Some
registers require being treated as volatile from the hosts perspective
even in their Access Mode is Read-Write. Add an explicit list of SDCA
controls that should be forced volatile.
