Josef Filzmaier ea23c905d3 atusb/fw: Introduction of a new board named HULUSB
The Busware HUL v1.1 dongle is a product very similar
to the rzusb dongle but with the at86rf212 instead of
the at86rf230 transceiver.

Some code refactoring has been made in order to better
support multiple hardware targets. This includes:

The reset_rf functions are now in the board specific files.
The led functions are now in the board specific files.
The register read/write functions are moved from mac.c to the generic
board.c file as they are used by functions like reset_rf that are
not within the mac.c file. Also the subreg_read and subreg_write
functions were introduced for convenience.
The function to change state is now also in board.c.

The hardware types are moved into the atusb.h file (which is always
synchrornized with the linux atusb driver) because they are now used
by the driver to identify and configure the hardware.

Within the makefile a new target name is specified called: hulusb
