The fw_attributes_class provides a much cleaner interface to all of the
attributes introduced to asus-wmi. This patch moves all of these extra
attributes over to fw_attributes_class, and shifts the bulk of these
definitions to a new kernel module to reduce the clutter of asus-wmi
with the intention of deprecating the asus-wmi attributes in future.
The work applies only to WMI methods which don't have a clearly defined
place within the sysfs and as a result ended up lumped together in
/sys/devices/platform/asus-nb-wmi/ with no standard API.
Where possible the fw attrs now implement defaults, min, max, scalar,
choices, etc. As en example dgpu_disable becomes:
/sys/class/firmware-attributes/asus-armoury/attributes/dgpu_disable/
├── current_value
├── display_name
├── possible_values
└── type
as do other attributes.
