Pull up following revision(s) (requested by jmcneill in ticket #101):
        sys/dev/fdt/gpiokeys.c: revision 1.3
        sys/dev/fdt/gpiokeys.c: revision 1.4
Read the initial key state at startup so we only trigger events on state
changes. Prevents a misconfigured power button from shutting us down at
boot.
Only read gpio pin if the pin is valid
