viafb: rework color setting
This is a rewritten version of viafb_setcolreg. The hardware register
writes were split up and moved to hw.c where they belong as this is really
low level stuff. It was made dual fb aware.
Furthermore viafb_setcmap was removed as the problem with 8bpp originated
from a bug in writing multiple color registers at once. The removal of
viafb_setcmap might introduce a small performance regression but its
certainly better to receive the correct result a bit slower than a garbled
picture fast. It should give us a working 8bpp mode and is more
extensible than the old hardcoded code. No other regressions are expected
but as the hardware might be a bit picky it might cause some regressions
in 8bpp mode on some hardware although I doubt that.
