[PATCH] xen/ACPI: Remove acpi_get_pxm() entirely

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

There are no callers, and the non-stub implementation is #if 0'd out, with the
internal trying to perform an AML invocation.

There's no plausible way that code is getting un-#if 0'd, so drop it.

No functional change.
