[PATCH] regulator: core: Use the power efficient workqueue for delayed powerdown

[Mark Brown]

From: Mark Brown <broonie@xxxxxxxxxx>

There is no need to use a normal per-CPU workqueue for delayed power downs
as they're not timing or performance critical and waking up a core for them
would defeat some of the point.
