oops hdmi

RV790  running drm-next as it was on 260613

Have used echo mem > /sys/power/state for some time now, though I don't think
this is a regression - just a situation that I haven't hit before.

Haven't tested every senario but it seems that if I boot and use single DVI
monitor then someone else turns on TV which is connected DVI -> hdmi then if I
use mem sleep I get an oops. If the TV is on already when I boot it doesn't
happen. I am not enabling the TV with xrandr as it's not me that is using it.
