Pull ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to upstream revision
  20170119, which among other things updates copyright notices in all of
  the ACPICA files, fix a couple of issues in the ACPI EC and button
  drivers, fix modalias handling for non-discoverable devices with
  DT-compatible identification strings, add a suspend quirk for one
  platform and fix a message in the APEI code.

  Specifics:

   - Update of the ACPICA code in the kernel to upstream revision
     20170119 including:

      + Fixes related to the handling of the bit width and bit offset
        fields in Generic Address Structure (Lv Zheng)
      + ACPI resources handling fix related to invalid resource
        descriptors (Bob Moore)
      + Fix to enable implicit result conversion for several ASL library
        functions (Bob Moore)
      + Support for method invocations as target operands in AML (Bob
        Moore)
      + Fix to use a correct operand type for DeRefOf() in some
        situations (Bob Moore)
      + Utilities updates (Bob Moore, Lv Zheng)
      + Disassembler/debugger updates (David Box, Lv Zheng)
      + Build fixes (Colin Ian King, Lv Zheng)
      + Update of copyright notices in all files (Bob Moore)

   - Fix for modalias handling for SPI and I2C devices with
     DT-compatible identification strings (Dan O'Donovan)

   - Fixes for the ACPI EC and button drivers (Lv Zheng)

   - ACPI processor handling fix related to CPU hotplug (online/offline)
     on x86 (Vitaly Kuznetsov)

   - Suspend quirk to save/restore NVS memory over S3 transitions for
     Lenovo G50-45 (Zhang Rui)

   - Message formatting fix for the ACPI APEI code (Colin Ian King)"
