drm/switcheroo: track state of switch in drivers.
We need to track the state of the switch in drivers, so that after s/r we don't resume the card we've explicitly switched off before. Also don't allow a userspace open to occur if we've switched the gpu off. Signed-off-by: Dave Airlie <airlied@redhat.com>
