Subject: ALSA: hda - Merge RIRB_PRE_DELAY into CTX_WORKAROUND caps
From: Takashi Iwai <tiwai@xxxxxxx>
commit ef85f299c74e6c5dd98ec0230183be33f4c2813d upstream.
AZX_DCAPS_RIRB_PRE_DELAY is always tied with AZX_DCAPS_CTX_WORKAROUND,
which is Creative's XFi specific. So, we can replace it and reduce
one more bit free for DCAPS.
