[PATCHv2] ARM: mvebu: Add DT entry for ReadyNAS Duo v2 to use gpio-poweroff driver

[Arnaud Ebalard]

Without that fix, at the end of the shutdown process, the board is
still powered (led glowing, fan running, ...).

Signed-off-by: Arnaud Ebalard <arno at natisbad.org>

Changes since v1:
 - use macro instead of value for GPIO voltage level
