I'm not completely sure about this patch since the code since impact is small (100 byte or so on ARM) and it might need splitting into smaller patches. But for now here it is.

Convert cmd_usage() calls in common to use a return value

Change all files in common/ to use CMD_RET_USAGE instead of calling
cmd_usage() directly. I'm not completely sure about this patch since
the code since impact is small (100 byte or so on ARM) and it might
need splitting into smaller patches. But for now here it is.

gpio: check request result

Make sure the pin request passed before attempting to use it later on.

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.
