drm/i915/display: Add mechanism to use sink model when applying quirk

Browse source

Currently there is no way to apply quirk on device only if certain panel
model is installed. This patch implements such mechanism by adding new
quirk type intel_dpcd_quirk which contains also sink_oui and sink_device_id
fields and using also them to figure out if applying quirk is needed.

New intel_init_dpcd_quirks is added and called after drm_dp_read_desc with
proper sink device identity read from dpcdc.

v3:
  - !mem_is_zero fixed to mem_is_zero
v2:
  - instead of using struct intel_quirk add new struct intel_dpcd_quirk
