fw/abb/twl3025: handle interrupt on powerbutton press
Since the powerbutton on the Pirelli DP-L10 doesn't seem to be
connected to the keypad scan matrix at all, we're using Iota's
PWON interrupt to determine if the powerbutton has been pressed,
and power off the phone after it has been released again.
This also affects the Compal phones, since the interrupt happens
quite some time before the keypad driver notices the keypress.
The code in the keypad driver that has been used so far to power
off the phone will remain as a backup when running without
interrupts at all (e.g. the loader application).
