dt-bindings: usb: Clean-up "usb-phy" constraints
Commit Message
"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.
