nv30: Fix color resolving for nv3x cards
We do not have a generic blitter on nv3x cards, so we must use the
sifm object for color resolving.
This commit divides the sources and dest surfaces in to tiles which
match the constraints of the sifm object, so that color resolving
will work properly on nv3x cards.
