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 later
patches.

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.

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.
