Subject: [PATCH 7/8] rfkill: add an "any radio" switch type and functionality

Add a RFKILL_TYPE_ANY switch.  This switch can control more than one type
of radio, and it is always subject to toggling by any type of rfkill-input
event.  It is suitable to implement kill-all-radios functionality when
coupled with input event EV_SW SW_RADIO.
