Subject: [PATCH v1] HID: Asus: add Z13 folio to generic group for multitouch
 to work

The Asus Z13 folio has a multitouch touchpad that needs to bind
to the hid-multitouch driver in order to work properly. So bind
it to the HID_GROUP_GENERIC group to release the touchpad and
move it to the bottom so that the comment applies to it.

While at it, change the generic KEYBOARD3 name to Z13_FOLIO.
