Introduce a common schema for DPLL pin consumers. Devices such as Ethernet
controllers and PHYs may require connections to DPLL pins for Synchronous
Ethernet (SyncE) or other frequency synchronization tasks.

Defining these properties in a shared schema ensures consistency across
different device types that consume DPLL resources.
