[Voyage-linux] LEDs and ledtrig stuff on APU

[Jordi Ferrer Plana]

I've patched an already existing driver for the AMD 50 FCH present in the
APU board for using the GPIO (3 OUTs + 1 IN).
I also have implemented a driver for using the LEDs and the switch
connected to these GPIOs using the leds-gpio interface,
so hardrive, heartbeat, network, ... and other events can be mapped to
these leds.
To make everything work I had to pach the watchdog driver sp5100_tco as
well.

So you could use directly the GPIO interface or the LEDs interface
depending on your needs.
I've been testing all this stuff on the voyage 0.9.2 (amd64) + kernel
3.10.11. It seems to work fine.
I attach the patch that can be applied directly to the
linux-source-3.10.11-voyage and the patch for the config-3.10.11-voyage.

There is no major changes between kernel 3.10.11 and the last 3.15 related
to the GPIO/LEDs interfaces and drivers, so with
very few changes (in some Makefile) the same patch can be modified to be
applied to any kernel from 3.10.11 to 3.15.
