ARM: mvebu: fix ReadyNAS 102 Power button GPIO to make it active high

NETGEAR ReadyNAS 102 Power button definition in .dts file flags associated GPIO active low instead of active high. This results in reversed events reported by input subsystem (0 returned when the button is pressed, 1 when released). This patch makes associated GPIO active high to recover correct behaviour.

---
RN102 .dts file sits in Linus tree only since 3.12-rc1 so I guess no one has currently relied on current reversed behaviour, i.e. this can be fixed w/o impact on any userspace program. As a side note, the initial error is mine.
