ASoC: arizona: Implement stability check for EQ coefficients

Browse source 
Specifying unstable coefficients for the EQ can have a severe impact on
the audio. This patchs adds a stability check on the coefficients
written to the EQ, for this it is necessary to merge the mode control
and the coefficients as some coefficients may only be unstable with a
certain mode setting so it is ideal if these are always updated in sync.
