xen/ACPI: Remove acpi_get_pxm() entirely
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. Signed-off-by: Andrew Cooper <andrew.cooper3@citrix.com> Acked-by: Jan Beulich <jbeulich@suse.com>
