ALSA: hda: Update register polling macros
Recent commitd91857059d
("ALSA: hda: Rework snd_hdac_stream_reset() to use macros") missed that on some devices register access needs to be done with unaligned access helper. Change polling macros to use read_poll_timeout_atomic() in order to specify register read function. Fixes:d91857059d
