LED framework

[Sascha Hauer]

Hi All,

The following series adds generic LED support for barebox.
Included is an infrastructure to register gpios as LEDs and
generic triggers for LEDs (Heartbeat, network activity). LEDs and
triggers can be controlled in C code and also on the command line.

The last patch only contains a small usage example, I'm not going
to commit it.

I have implemented this patchset completely remote with printfs in
the gpio functions, so I haven't seen any LED blinking. I hope that
the triggers are not too short for a LED to actually blink.
