ALSA: hda: track CIRB/CORB command/response states for each codec
Recently we hit a bug in our dev board, whose HDMI codec#3 may emit redundant/spurious responses, which were then taken as responses to command for another onboard Realtek codec#2, and mess up both codecs. Extend the azx_rb.cmds and azx_rb.res to array and track each codec's commands/responses separately. This helps keep good codec safe from broken ones.
