gma500: Consider CRTC initially active.
[this one ideally should make 3.6 - it fixes the very annoying mode setting bug] This causes the pipe to be forced off prior to initial mode set, which roughly mirrors the behavior of the i915 driver. It fixes initial mode setting on my Intel DN2800MT (Cedarview) board. Without it, mode setting triggers an out-of-range error from the monitor for most modes, but only on initial configuration (i.e. they can be configured successfully from userspace after that).
