cirrusfb: various Laguna fixes
- The Laguna GD5465 (AGP) has one register more than non-AGP chips.
Recognize the AGP version and write a tile control register only on the
AGP version. Tested only on an AGP card.
- Bump up RAMDAC frequencies after X11 code. This allow to drive a flat
panel resolution 1680x1050 at 16bpp from the 4MB card.
- Fix screen start address overflow bits on Laguna cards (CRT1D
register).
- Fix exit path in the cirrusfb_pci_register() in case of error.
