[PATCH v6 0/6] platform/x86: Add Lenovo WMI Gaming Series Drivers

["Derek J. Clark" <derekjohn.clark@gmail.com>]

Adds support for the Lenovo "Gaming Series" of laptop hardware that use
WMI interfaces that control various power settings. There are multiple WMI
interfaces that work in concert to provide getting and setting values as
well as validation of input. Currently only the "Gamezone", "Other
Mode", and "LENOVO_CAPABILITY_DATA_01" interfaces are implemented, but
I attempted to structure the driver so that adding the "Custom Mode",
"Lighting", and other data block interfaces would be trivial in a later
patches.

This driver is distinct from, but should be considered a replacement for
this patch:

This driver attempts to standardize the exposed sysfs by mirroring the
asus-armoury driver currently under review. As such, a lot of
inspiration has been drawn from that driver.

The drivers have been tested by me on the Lenovo Legion Go and Legion Go
S.

v6:
 - Capability Data max values are determined based on the power state of the device.
   To ensure this data is accurate, recache capability data on ACPI AC/DC events.
 - Use guard/scoped guard in gamzone driver.
 - Use correct types for casts and sizeof in some places.
 - Fix formatting issues identified in v5.
