v6 -> v7:
- add Igor's R-b

v5 -> v6:
- fix mingw compil issue

v4 -> v5:
- Align to x86 code and especially
  "pc: acpi: revert back to 1 SRAT entry for hotpluggable area"

v3 -> v4:
- do not use vms->bootinfo.device_memory_start/device_memory_size anymore

v1 -> v2:
- build_srat_hotpluggable_memory movedc to aml-build
