    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.
