Move the MARK_GRAPHICS_MEM_WRCOMB to x86 architecture 

The MARK_GRAPHICS_MEM_WRCOMB was spreading like a cancer
since it was defined in sandybridge. It is really
more of an x86 thing however, and we now have
three systems that can use it.

I considered making this more general, since it technically
can apply to PTE-based systems like ARM, and maybe we should.
But the 'WRCOMB' moniker is usually closely tied to the x86.
