x86: pci: acpi: reorder Device's _ADR and _SUN fields
no functional change, align order of fields in empty slot
descriptor with a populated slot ordering.
Expected diff:
- Name (_SUN, 0x0X) // _SUN: Slot User Number
Name (_ADR, 0xY) // _ADR: Address
...
+ Name (_SUN, 0xX) // _SUN: Slot User Number
that will eliminate contextual changes (causing test failures)
when follow up patches merge code generating populated and empty
slots descriptors.
Put mandatory _ADR as the 1st field, then ASUN as it can be
present for both pupulated and empty slots and only then _SUN
which is present only when slot is hotpluggable.
