On broken EDID we were reporting vga connector to be disconnected
even if ddc probe did found a monitor. This patch report that the
connector is connected on such case. This allow drm to add a fail
safe mode (800x600 at the time of this patch) thus user can boot
and later add a mode which match its monitor capabilities.
