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. ] Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Mike Travis <mike.travis@hpe.com> Signed-off-by: Borislav Petkov <bp@suse.de> Reviewed-by: Steve Wahl <steve.wahl@hpe.com> Link: https://lkml.kernel.org/r/20201005203929.148656-5-mike.travis@hpe.com
