drm/amd/display: set panel orientation before drm_dev_register

To set the panel orientation property with quirk, we need the mode size
provided by EDID. This info is available after EDID is read by dc_link_detect()
and updated by amdgpu_dm_update_connector_after_detect(). The detection
happens at driver load in amdgpu_dm_initialize_drm_device() and,
therefore, we can get modes and set panel orientation before
drm_dev_register() to avoid DRM warns on creating the connector property
after device registration:
