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.

This is kinda a big patch that I feel might have done some justice to
split into smaller logical pieces. These are much easier to review.
For example:
1) You've clearly got 3 "groups" of attributes, maybe those should come
in a separate series each.
2) Some of the helper functions that are exported should be exported in
their own patches (for example asus_wmi_get_devstate_dsts)
3) panel_hd_mode is a new attribute not leveraged from asus-wmi AFAICT,
with a new define. It probably could have been it's own patch to "add
panel_hd_mode".
More comments inline below.

I go back and forth on the existence of tuning knobs for all these
values. As a tinkerer it's of course nice to see so many knobs.
However thinking about how this would be exposed to userspace and what
users will drag for a "slider" for performance it's really confusing.
Which knob is tuned? What's different for CPU vs platform? What's slow
vs fast?
As a result, I think I would rather see these (specifically) relegated
to debugfs attributes and instead export an ACPI platform profile. The
ACPI platform profile can then give users a clearer set of expectations; IE:
"power-saver", "balanced", "performance"
Bifurcating it this way will enable both audiences. The people who want
to drag a slider in a UI to save power or consume power can do so, and
those that know what all these mean and want to spend more time
tinkering can go to debugfs to do so.
But with this idea there would essentially be two sets of knobs that
change the same thing. So I think that if the debugfs knobs were tuned
away from the defaults the platform profile needs to be reset to an error.
