platform/x86: asus-wmi: deprecate bios features

With the existence of the asus-armoury module the attributes no longer
need to live under the /sys/devices/platform/asus-nb-wmi/ path.

Deprecate all those that were implemented in asus-bioscfg with the goal
of removing them fully in the next LTS cycle.
