PATCH 1/2 gma500: Oaktrail fixes

From: Alan Cox <[email protected]>

The move to connectors breaks Oaktrail again if we have memory poisoning enabled. Fix this.

PATCH 2/2 oaktrail: panel display quality fix

From: Alan Cox <[email protected]>

The GCT setup was used on Moorestown. The Oaktrail version uses a normal PC interface. That means we must also honour the dither info from the BIOS data.
