ALSA: hda: Add Lisuan HDMI controller and codec support

Browse source

Lisuan GPUs expose an HD-audio controller at PCI ID 4c54:5010 and an
HDMI/DP codec with codec ID 0x4c545020.  Neither ID is currently matched
by the HDA stack, leaving HDMI/DP audio unavailable on these devices.

The existing downstream support uses the generic HDMI codec path and
attaches no Lisuan-specific capability flags to the controller.  Its
dedicated AZX driver type only changes the short driver name.

Use the corresponding generic upstream paths instead: bind 4c54:5010 to
AZX_DRIVER_GENERIC, register 0x4c545020 as MODEL_GENERIC, and add the
Lisuan codec vendor name.  This keeps the enablement minimal and avoids
a vendor-only AZX driver type with no vendor-specific behavior.
