Blackfin: move on-chip UART resources to boards files
Rather than keeping the pins in the actual driver and worrying about a
mess of Kconfig options, declare all the desired pin resources in the
boards file. This lets people easily select the specific pins/ports for
the normal UART as well as GPIOs for CTS/RTS.
