Blackfin: bf538: add support for extended GPIO banks
The GPIOs on ports C/D/E on the BF538/BF539 do not behave the same way as the other ports on the part and the same way as all other Blackfin parts. The MMRs are programmed slightly different and they cannot be used to generate interrupts or wakeup a sleeping system. Since these guys don't fit into the existing code, create a simple gpiolib driver for them.
