Subject: [PATCH] ALSA: HDA: Add Zhaoxin HDMI Controller and Codec support

Add newer Zhaoxin HD Audio PCI IDs, and HDMI codec vendor IDs.

Because Zhaoxin hardware limitation, set BDL position to 128 to
increase interrupt interval.

To fix response write request not synced to memory when handle
HDAC interrupt, set bus->polling_mode = 1.
