usb: phy: Add interface to get phy give of device_node.
Split the "get phy from device_node" functionality out of
"get phy by phandle" so it can be used directly.
This is useful when a battery-charger is intimately associated with a
particular phy but handled by a separate driver. The charger
can find the device_node based on sibling relationships
without the need for a redundant declaration in the devicetree
description.
As a peripheral that gets a phy will often want to register a
notifier block, and de-register it later, that functionality
is included so the de-registration is automatic.
