Patch file cleanup

Do a couple things here:

- Split the mega-patches into individual patches.  Should help with rebasing.
- Make all patches 'git am' acceptable.

There should be no functional or actual code differences from before

+Subject: [PATCH] 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.
