ALSA: hda: Fix several mismatch for register mask and value

Browse source 
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.
