Aaron Durbin b489622a1f 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.
