ALSA: hda: Fix several mismatch for register mask and value
E.g. for snd_hdac_ext_link_clear_stream_id(), we should set (1 << stream) as mask, and 0 as value, here correct it and several similar mismatches. And, here also remove unreadable register_mask usage for those mask value updating. Signed-off-by: Keyon Jie <yang.jie@linux.intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
