drm/vmwgfx: Refactor drm connector probing for display modes
[ Upstream commit 935f795045a6f9b13d28d46ebdad04bfea8750dd ]
Implement drm_connector_helper_funcs.mode_valid and .get_modes,
replacing custom drm_connector_funcs.fill_modes code with
drm_helper_probe_single_connector_modes; for STDU, LDU & SOU
display units.
