x86/platform/uv: Update UV MMRs for UV5
Update UV MMRs in uv_mmrs.h for UV5 based on Verilog output from the
UV Hub hardware design files. This is the next UV architecture with
a new class (UVY) being defined for 52 bit physical address masks.
Uses a bitmask for UV arch identification so a single test can cover
multiple versions. Includes other adjustments to match the uv_mmrs.h
file to keep from encountering compile errors. New UV5 functionality
is added in the patches that follow.
[ Fix W=1 build warnings. ]
