Add the code for getting generic PHYs from standard device tree array from the main controller device node. This is a first step in resolving the conflict between Exynos EHCI/OHCI sub-nodes and generic USB device bindings. Later the sub-nodes currently used for assigning PHYs to root ports of the controller will be removed making a place for the generic USB device bindings nodes.
