Mike Travis acb8be461b x86: SGI UV: Fix writes to led registers on remote uv hubs
commit 39d3077099 upstream.

The wrong address was being used to write the SCIR led regs on
remote hubs.  Also, there was an inconsistency between how BIOS
and the kernel indexed these regs.  Standardize on using the
lower 6 bits of the APIC ID as the index.

This patch fixes the problem of writing to an errant address to
a cpu # >= 64.
