Iinitial hks rfkill driver
Some initial rfkill drivers, mostly here so i get up to date debs (i only tested on linux-next so far) and have something to link to.
Note that adding the camera is uabi change so we likely want to skip that until merged upstream (also camera is not really rfkll so we might end up handling this as a button - i'll bring that upstream once the driver is suitable).
Known deficiencies:
- can only bind a single GPIO to a rfkill. This can be fixed by switching to bitflags in
include/dt-bindings/rfkill/rfkill.h
but since this needs more work (#256 ) we can defer it - binding docs (same reasoning as above)
