ALSA: hda/cs35l56: Do not mark cache dirty after REINIT

Only call regcache_mark_dirty() in cs35l56_hda_fw_load() if
the CS35L56 was SYSTEM_RESET.

recache_mark_dirty() changes the behaviour of regcache_sync()
to write out cache values that are not the default value, and
skip cache values that are the default.

AUDIO_REINIT does not reset the registers. regcache_mark_dirty()
after AUDIO_REINIT could cause the regcache_sync() to sync
registers incorrectly because it will assume that all registers
have reset to default.
