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.

Hi Derek,

Could you please rebase this on top of for-next placing the files under 
lenovo/ folder which we just created. I could have easily changed the 
placement of the files themselves, but making the Kconfig & Makefile 
changes into the new files while applying would have been more 
complicated. It is better you do it so I won't end up messing up anything.

There's the lenovo-target in lenovo/Makefile which will auto add the 
'lenovo-' prefix to the files so you can basically rename the files like 
this:

drivers/platform/x86/lenovo-wmi-other.c ->
drivers/platform/x86/lenovo/wmi-other.c

...and add them using that lenovo-target.

Sure. I'm on travel so it may be a few days. I'll attempt to get it done today if I can though.

Should I change the docs at all for this?
