[PATCH v2 0/6] platform/x86: introduce asus-armoury

["Luke D. Jones" <luke@ljones.dev>]

This is the first major patch I've ever done with the intention of
introducing a new module, so it's highly likely I've made some mistakes
or misunderstood something.

TL;DR:
1. introduce new module to contain bios attributes, using fw_attributes_class
2. deprecate all possible attributes from asus-wmi that were added ad-hoc
3. remove those in the next LTS cycle

The idea for this originates from a conversation with Mario Limonciello
https://lore.kernel.org/platform-driver-x86/371d4109-a3bb-4c3b-802f-4ec27a945c99@amd.com/

It is without a doubt much cleaner to use, easier to discover, and the
API is well defined as opposed to the random clutter of attributes I had
been placing in the platform sysfs.

The name `asus-armoury` was settled on after some debate with users of the module.
This name is derived from the ASUS application named "Armoury Crate" as this is what
many users look for in searches and articles when crossing over to Linux from Windows.
The alternative was `asus-fw-settings`, which may still be up if there is any opposition
to the new name.

I am unsure of how best to handle the deprecation of attributes.

There's also some attributes that are obviously boolean but are using 0/1.
I'm unsure if I should change that.

And would it be best to move the asus stuff to a subdir now? Akin to the
Dell platform stuff.

The two new files were formatted with clangd with line length 96

I get this with checkpatch:
```
ERROR: Macros with multiple statements should be enclosed in a do - while loop
#934: FILE: drivers/platform/x86/asus-armoury.h:116:
+#define ATTR_GROUP_ENUM_INT_RO(_attrname, _fsname, _wmi, _possible, _dispname) \
+	__ATTR_CURRENT_INT_RO(_attrname, _wmi);                                \
+	__ATTR_GROUP_ENUM(_attrname, _fsname, _possible, _dispname)
```
I'm unsure what to do - adding the do/while breaks things.

All guidance deeply appreciated to get this over the line.

Regards,
Luke
