Subject: [PATCH v5 0/6] platform/x86: Add Lenovo Gaming Series WMI Drivers

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@163.com/

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@ljones.dev/

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

v5:
 - Adjusted patch order to put lenovo-wmi-other last. Also added the
   references to lenovo-wmi-other in lenovo-wmi-gamezone in that patch.
 - No longer using devm_kmalloc_array in the bind function for capdata
   and other drivers. Instead, a pointer to the list in capdata01 is
   passed back to other.
 - Disambiguated most constants and defines to better indicate they are
   part of the lenovo-wmi drivers and thier function.
 - Ensured the firmware attributes for other are removed on component
   unbind.
 - Various misc formatting fixes from v4.
