Refactor out the _PXM -> VM domain lookup done in ACPI, in preparation for
its use in upcoming code.
This is inspired by something in jhb's NUMA IRQ allocation patchset.
However, the tricky bit here is that the PXM lookup for a node may
fail, requiring a lookup on the parent node. So if it doesn't
exist, don't fail - just go up to the parent. Only error out of the
lookup is the ACPI lookup returns an error.
