[PATCH v3 0/6] platform-x86: lenovo-wmi: Add fixes and enhancement

This series adds many much needed features and fixes to the lenovo-wmi
drivers.

Patch 1 adds a macro to make assigning attribute ID's for capdata
cleaner and easier.
Patch 2 addresses bugs where devices that don't support exposed
attributes would still create the attribute, and also attempts to
identify the correct capdata and set/get methods as some legacy
interfaces don't use the custom mode in the method or capdata ID.
Patch 3 adds the remaining CPU attributes that weren't previously
exposed.
Patch 4 adds the GPU attributes that weren't previously exposed.
Patch 5 consolidates name constants in preparation for patch 6.
Patch 6 adds battery charge-type limiting when supported only by WMI.

After applying Rong's series from
https://lore.kernel.org/platform-driver-x86/20260210191938.137234-1-i@rong.moe/
I found that there weren't any conflicts, so rather than combine
the series we can just review each separately.

v3:
- Re-add HWMON name const and jsut rename LWMI_OM_FW_ATTR_BASE_PATH
- Fix linker warnings by moving acpi/battery include to the end of the
list.
- Remove CPU/GPU OC features. These attributes are BOOL type and will
need a new constructor that I'll add later.
v2:
- Fix gpu_mode misisng from attributes list.
- Fix prototypes for power suppy patch.
- Reorganize CPU and GPU attributes alphabetically.
- Break out the patch consolidating the driver name cost.
- Move some of the refactoring of attribute_id back to into patch 1
where it belongs.
- Fix some additional typos in function prototypes.
v1: https://lore.kernel.org/platform-driver-x86/20260213081243.794288-1-derekjohn.clark@gmail.com/
