Dmesg of regression: 3.7-rc8+nouveau(implement opcode 0xa9)

Commit:

767baf828498: drm/nouveau: remove some more unnecessary legacy bios code

causes a regression. Attached are dmesg logs and photographs (since the title
probably won't cut it).

Symptoms are:

- screen is dislocated to the right causing part of the screen to fall off
- the part that falls of the screen is improperly repainted on the left side,
seems like a mirror effect in that this repainting is happening twice
- upper part of the screen has a horizontal bar that is probably 1 or 2 pixels
thick. Desktop is displayed there, but it's scrambled.

This is with an 'C51 (NV4E)' chipset.

Mupuf on #nouveau mentioned removing the ' #if 0 / #endif ' parts in this
commit and see if that rebuilds. I added 'pll_limit_tbl_ptr' back to
nouveau_bios.h to make it compile. This does not help. Bug is still there. The
dmesg log 'attempt' contains the dmesg output with this modification.

Mupuf also mentioned that 'it clearly is a PLL calculation problem'. Therefore,
I also refer back to previous fdo bug #56202 . This was also related to 'PLL'
(I have no idea what it is though)...
