KMS drivers really should all be able to restore their display state

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

It looks somewhat obvious for that, as the Rockchip setting was true
from the beginning, but I still gave it some suspend-spins on rk3399
so as well
