Commit bca5f557dcea "ACPI / processor: Make acpi_processor_ppc_has_changed()
void" changed one of the declarations of acpi_processor_ppc_has_changed()
to return void, but the !CPU_FREQ version still returns int. Let's return
void to be consistent.

 "These update the ACPICA code in the kernel to upstream revision
  20180531 including one important AML parser fix and updates related to
  the IORT table, make the kernel recognize the "Windows 2017.2" _OSI
  string and update the customized methods documentation.

  Specifics:

   - Update the ACPICA code in the kernel to upstream revision 20180531
     including:

PMCG nodes were added by IORT revision C, with the unfortunate oversight
that it only defined a single base address, and thus was incapable of
properly describing PMCG implementations with PMCG_CFGR.RELOC_CTRS = 1,
where the counters are in a separate page from the control registers.

Revision D corrects this by clarifying the existing field as the page 0
base address and adding a second field to describe the page 1 address
when implemented. With the spec now fit for purpose, let's support it.

IORT revision D contains a few additions and fixes to
currently-supported tables:

- SMMUv3 proximity domain field is enlarged to 4 bytes for consistency
  with SRAT
- Root complex nodes gain an address size limit field equivalent to that
  of named components
- Named component nodes gain a way to describe PASID (substream_ID)
  support, encoded in their flags

Additionally, we fix a couple of outstanding points in passing:
- Add the stall support flag for named components defined in revision C
- Fix SMMUv3 HTTU override mask, which should always have been 2 bits
