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.
