x86: SGI UV: Map low MMR ranges

Browse source

Explicitly mmap the UV chipset MMR address ranges used to
access blade-local registers. Although these same MMRs are also
mmaped at higher addresses, the low range is more
convenient when accessing blade-local registers.

The low range addresses always alias to the local blade
regardless of the blade id.
