ALSA: hda: Use regcache_reg_cached() rather than open coding
The HDA driver intentionally drops repeated writes to registers in some
circumstances, beyond the suppression of noop writes that regmap does in
regmap_update_bits(). It does this by checking if the register is cached
before doing a regmap_update_bits(), now we have an API for querying this
directly use it directly rather than trying a read in cache only mode
making the code a little clearer.
