Add a memory-range interface to /dev/mem on PowerPC using PAT attributes.
Unlike actual MTRR, this only controls the mapping attributes for
subsequent mmap() of /dev/mem. Nonetheless, the support is sufficiently
MTRR-like that Xorg can use it, which translates into an enormous increase
in graphics performance on PowerPC.
MFC after: 2 weeks
