Ethernet controllers may be connected to DPLL (Digital Phase Locked Loop) pins for frequency synchronization purposes, such as in Synchronous Ethernet (SyncE) configurations. Add 'dpll-pins' and 'dpll-pin-names' properties to the generic ethernet-controller schema. This allows describing the physical connections between the Ethernet controller and the DPLL subsystem pins in the Device Tree, enabling drivers to request and manage these resources.
