UBUNTU: SAUCE: UEFI: asus-wmi: Restrict debugfs interface when module loading is restricted

We have no way of validating what all of the Asus WMI methods do on a
given machine, and there's a risk that some will allow hardware state to
be manipulated in such a way that arbitrary code can be executed in the
kernel, circumventing module loading restrictions. Prevent that if any of
these features are enabled.
