ACPI updates for v4.15-rc1

Browse source 
- Update the ACPICA code to upstream revision 20170831 including
    * PDTT table header support (Bob Moore).
    * Cleanup and extension of internal string-to-integer conversion
      functions (Bob Moore).
    * Support for 64-bit hardware accesses (Lv Zheng).
    * ACPI PM Timer code adjustment to deal with 64-bit return values
      of acpi_hw_read() (Bob Moore).
    * Support for deferred table verification in acpiexec (Lv Zheng).
 
  - Fix APEI to use the fixmap instead of ioremap_page_range() which
    cannot work correctly the way the code in there attempted to use
    it and drop some code that's not necessary any more after that
    change (James Morse).
 
  - Clean up the APEI support code and make it use 64-bit timestamps
    (Arnd Bergmann, Dongjiu Geng, Jan Beulich).
 
  - Add operation region driver for TI PMIC TPS68470 (Rajmohan Mani).
 
  - Add support for PCC subspace IDs to the ACPI CPPC driver (George
    Cherian).
 
  - Fix an ACPI EC driver regression related to the handling of EC
    events during the "noirq" phases of system suspend/resume (Lv
    Zheng).
 
  - Delay the initialization of the lid state in the ACPI button
    driver to fix issues appearing on some systems (Hans de Goede).
 
  - Extend the KIOX000A "device always present" quirk to cover all
    affected BIOS versions (Hans de Goede).
 
  - Clean up some code in the ACPI core and drivers (Colin Ian King,
    Gustavo Silva).

Merge tag 'acpi-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
 "These update ACPICA to upstream revision 20170831, fix APEI to use the
  fixmap instead of ioremap_page_range(), add an operation region driver
  for TI PMIC TPS68470, add support for PCC subspace IDs to the ACPI
  CPPC driver, fix a few assorted issues and clean up some code.

  Specifics:

   - Update the ACPICA code to upstream revision 20170831 including
      * PDTT table header support (Bob Moore).
      * Cleanup and extension of internal string-to-integer conversion
        functions (Bob Moore).
