drm/fbdev: Make skip_vt_switch the default
KMS drivers really should all be able to restore their display state
on resume without fbcon helping out. So make this the default.
Since I'm not entirely foolish, make it only a default, which drivers
can still override. That way when the inevitable regression report
happens I can fix things up with a one-liner plus FIXME comment that
someone should fix up the suspend/resume code in that driver.
But at least all new drivers won't be broken by accident as soon as
you turn off fbcon because "suspend/resume worked when I tested it".
v2: Keep this for radeon because of
