Couple of changes in the video side.
...
1. Second attempt to fix the banking in the Cirrus (sigh, why doesn't banking get nulled automatically...)
2. Introduce a new timer to the 8514/A side so it won't slow the VGA clock down it was shared before.

Update on Cirrus banking.
...
When I say banking should be 0 when IBM VGA modes are set, they must be, Cirrus...
Also, updated the vram mask using the gd54xx struct rather than svga's for consistency.

HDISP updates on S3 968 cards.

Attempt at fixing the half horizontal display bugs in the best possible way without affecting the vendor drivers (which don't enable bit 6 of gdcreg5 for 256 colors and greater but generic non-vendor specific drivers do).
