gpio: generalize for all generic gpio providers
The Blackfin gpio command isn't terribly Blackfin-specific. So generalize
the few pieces into two new optional helpers:
name_to_gpio() - turn a string name into a GPIO #
gpio_status() - display current pin bindings (think /proc/gpio)
Once these pieces are pulled out, we can relocate the cmd_gpio.c into the
common directory.
