xfree86: Clean up some more alpha awareness
Since the sparse stuff is gone none of these variables get used for
anything, they're just dead side-effect-less execution.

commit 2e21c081d34d52ee49ac00a294d2e74caf529818

xfree86: Remove the memory of MTRR awareness
pciaccess does this for us, and none of our internal hooks really
remain. This does remove a cleanup pass from the BSD code, but the case
it's covering (a previous server leaving MTRRs around) can't happen
anymore.

xfree86: Remove xf86{Map,Unmap}VidMem
This API sucks. Fortunately it's mostly unused at this point. geode,
sis, and xgi need minor patches to use the corresponding pciaccess code,
neomagic will (more explicitly) lose its non-PCI support, and newport
will need to be ported to /dev/mem or the platform bus or something.
This should also make it pretty clear that alpha's sparse memory support
was basically not a thing anymore, very few tears shed.
