Thomas Hellstrom cc0ba0d862 drm/vmwgfx: Use the backdoor port if the HB port is not available
The HB port may not be available for various reasons. Either it has been
disabled by a config option or by the hypervisor for other reasons.
In that case, make sure we have a backup plan and use the backdoor port
instead with a performance penalty.
