3.16.7-ckt15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: NeilBrown <neil@brown.name>

commit 4724e27114c4a7eceeee07db227a17fcab6f165c upstream.

The USB phy should initialize with power-off, and will be powered on
by the USB system when a cable connection is detected.

Having this pm_runtime_get_sync() during probe causes the phy to
*always* be powered on.
Removing it returns to sensible power management.
