blackfin: adi gpio driver and pinctrl driver support

Remove gpio driver for new gpio controller on BF54x and BF60x.
Build the bfin_gpio driver only when other BF5xx processors are selected.
Replace the prefix of some gpio and peripheral functions with adi.
add portmux platform data in machine portmux.h
