libflash: Reintroduce typesafety in lowlevel libflash calls
Previous work did away with some typesafety when adding the blocklevel_device abstraction, this has resulted in the ability to accidently call libflash low level code with a blocklevel_device which has not been initialised by the libflash backend. The end result will not be good. Best to reintroduce that low level calls be called with libflashes own structures.
