ALSA: hda: Glenfly: add HD Audio PCI IDs and HDMI Codec Vendor IDs.
Add a set of HD Audio PCI IDS, and the HDMI codec vendor IDs for
Glenfly Gpus.
- In default_bdl_pos_adj, set bdl to 128 as Glenfly Gpus have hardware
limitation, need to increase hdac interrupt interval.
- In azx_first_init, enable polling mode for Glenfly Gpu. When the codec
complete the command, it sends interrupt and writes response entries to
memory, howerver, the write requests sometimes are not actually
synchronized to memory when driver handle hdac interrupt on Glenfly Gpus.
If the RIRB status is not updated in the interrupt handler,
azx_rirb_get_response keeps trying to recevie a response from rirb until
1s timeout. Enabling polling mode for Glenfly Gpu can fix the issue.
- In patch_gf_hdmi, set Glenlfy Gpu Codec's no_sticky_stream as it need
driver to do actual clean-ups for the linked codec when switch from one
codec to another.
