rambi: don't mark graphics as write-combining
We are currently running out of MTRRs with this CPU when marking the graphics memory as write-combining. The reason is that the graphics stolen memory was bumped to 64MiB which changes the address space enough that the MTRRs are exhausted.
BUG=None BRANCH=None TEST=Built and analyzed MTRR usage. Also noted clearing upper 2GiB of memory in depthcharge does not take forever.
