95b4b9d97a Blackfin: gpio: optimize free path a little
When we aren't doing resource tracking, the gpio_free() function is a
stub that simply returns, so pull this logic up a level and make it an
inline stub in the header.  Now we don't have to waste time at any of
the call sites.

a972b8d701 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.

4638b21f2e Blackfin: import gpio/portmux layer from Linux
The current pinmux handling has spread throughout Blackfin drivers and
board code and is getting hideous to maintain.  So import the gpio and
portmux layer from the Blackfin Linux code.  This should spur a serious
of cleanups across the Blackfin tree.
