Add a Firmware programming framework
This framework handles a list of registered Firmware programming handlers
to unify a firmware programming interface by hiding the details how
to program a specific Firmware in its handler. This is created with FPGAs
in mind but should be usable for other devices aswell.
A user has two possibilities to load a firmware. A device file is create
under /dev/ which can be used to copy a firmware to. Additionally a
firmwareload command is introduced which can list the registered firmware
handlers and also to upload a firmware.
