[PATCH 12/17] x86: pci: acpi: reorder Device's _ADR and _SUN fields

[Igor Mammedov]

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.
