apalis_t30: implement optional force off gpio support
Both the Apalis EvalBoard as well as Ixora allow their LTC2954
pushbutton on/off controller to optionally be forced off by using a
GPIO. This patch implements this upon poweroff/shutdown using Apalis
GPIO6 which happens to be internally pulled-up upon power-on reset
(otherwise we would immediately get powered off again). For this to
work the following wiring is required:
Apalis EvalBoard V1.1a X2-A5 to X61-5
Ixora V1.0a X27-18 to X5-5
