Blackfin: import gpio/portmux layer from Linux
The current pinmux handling has spread throughout Blackfin drivers and board code and is getting hideous to maintain. So import the gpio and portmux layer from the Blackfin Linux code. This should spur a serious of cleanups across the Blackfin tree. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
