Pull more ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to upstream revision
  20170303 which adds a few minor fixes and improvements, update ACPI
  SoC drivers with new device IDs, platform-related information and
  similar, fix the register information in the xpower PMIC driver,
  introduce a concept of "always present" devices to the ACPI device
  enumeration code and use it to fix a problem with one platform, and
  fix a system resume issue related to power resources.

  Specifics:

   - Update the ACPICA code in the kernel to upstream revision 20170303
     which includes:
      * Minor fixes and improvements in the core code (Bob Moore,
        Seunghun Han).
      * Debugger fixes (Colin Ian King, Lv Zheng).
      * Compiler/disassembler improvements (Bob Moore, David Box, Lv
        Zheng).
      * Build-related update (Lv Zheng).

   - Add new device IDs and platform-related information to the ACPI
     drivers for Intel (LPSS) and AMD (APD) SoCs (Hanjun Guo, Hans de
     Goede).

   - Make it possible to quirk ACPI-enumerated devices as "always
     present" on platforms where they are incorrectly reported as not
     present by the AML and add the INT0002 device ID to the list of
     "always present" devices (Hans de Goede).

   - Fix the register information in the xpower PMIC driver and add
     comments to map the registers to symbols used by AML to it (Hans de
     Goede).

   - Move the code turning off unused ACPI power resources during system
     resume to a point after all devices have been resumed to avoid
     issues with power resources that do not behave as expected (Hans de
     Goede)"
