"usb-phy" has multiple type definitions. Unify the type with the looser definition, phandle-array, as there are cases with multiple entries (USB2 and USB3). However, the 'phandle-array' type alone is a bit ambiguous. It can be either just an array of phandles or an array of phandles plus args. "usb-phy" is the former and needs to constrain each entry to a single phandle value.
