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 Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Steven Miao <realmz6@gmail.com>
