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: https://lore.kernel.org/all/20241118100503.14228-1-jonmail@xxxxxxx/ 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. https://lore.kernel.org/platform-driver-x86/20250316230724.100165-1-luke@xxxxxxxxxx/ The drivers have been tested by me on the Lenovo Legion Go and Legion Go S.
