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

HI Jason and Andrew,
This is not per se a fix for a real problem, as the NAS runs
as expected w/o it, it only solves a minor limitation of the
shutdown process so I guess it can be queued for 3.13 if it
is too late.
Additionally, I wonder if I should send another patch to either have
ARCH_MVEBU select POWER_SUPPLY, POWER_RESET and POWER_RESET_GPIO,
or have mvebu_defconfig modified to enable those, or keep things as
they are until there are more users on mvebu.
