drm/amd/display: Update MST edid property every time
Extended fix to: "Don't read EDID in atomic_check"
Fix display property not observed in GUI display after hot plug.
Call drm_mode_connector_update_edid_property every time in
.get_modes hook, due to the fact that edid property is getting
removed from usermode ioctl DRM_IOCTL_MODE_GETCONNECTOR each time
in hot unplug.
