BeagleBone Black: GPIO configuration
I wanted to do this "safely", disallowing userspace from configuring the
input pins as outputs, etc., but no joy -- I don't think that Linux
really supports this.
So, this patch really just sets proper names for the GPIO lines that
we're using. The idea here is that the userspace will request those
lines by name and (hopefully) configure them properly without burning
anything (yay).
