x86/platform/UV: Fix problem with UV4 BIOS providing incorrect PXM values

There are some circumstances where the UV4 BIOS cannot provide the
correct Proximity Node values to associate with specific Sockets and
Physical Nodes.  The decision was made to remove these values from BIOS
and for the kernel to get these values from the standard ACPI tables.
