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)"
