VGA outs.
The drm_initial_config path has specific handling code to name
match for VGA, TMDS or LVDS. This is pretty restrictive and should
probably be dealt with to be more generic.
Check for the PENDING message when reading the attached
displays. Ensures the command has completed before continuing.
(probably need to check PENDING in other SDVO calls too)
