drm/amd/display: Fix EDID parsing after resume from suspend
[Why]
Resuming from suspend, CEA blocks from EDID are not parsed and no video
modes can support YUV420. When this happens, output bpc cannot go over
8-bit with 4K modes on HDMI.
[How]
In amdgpu_dm_update_connector_after_detect(), drm_add_edid_modes() is
called after drm_connector_update_edid_property() to fully parse EDID
and update display info.
