[PATCH] rivafb: directcolor mode and miscellaneous fixes

Although the rivafb advertises its capability as DirectColor, the hardware
is actually set in Truecolor (CLUT cannot be altered).  This mismatch
occasionally produces wrong colors, such as wrong logo colors at 32bpp and
gamma utilities (such as xgamma) does not work at all.

Changes:

1. Fixes the above problems by setting the hardware to accept changing
   of the CLUT.

2. Fixes color problems for NV_ARCH_03 (Riva128)

3. Build a private modelist from the EDID (for use by fbcon)

4. Mark several functions/data as __devinit/__initdata

5. Remove unused fields from struct riva_par
