Update with changes from RFC V2

Lots of new changes
* Move sp5100_tco patches to x86
* Enable the LED & GPIO driver within the kernel config
* Remove the Modules for sp5100_tco and gpio-nct5104d
* Add board detection code to gpio-nct5104d (needed as it's in the
kernel config now)
* Minor updates to leds-apu2
* Update build.sh to use latest revision
