Add helper functions to the DPLL core to retrieve a DPLL pin's firmware
node handle based on the "dpll-pins" and "dpll-pin-names" properties.

* `fwnode_dpll_pin_node_get()`: matches the given name against the
   "dpll-pin-names" property to find the correct index, then retrieves
   the reference from "dpll-pins".
* `device_dpll_pin_node_get()`: a wrapper around the fwnode helper for
   convenience when using a `struct device`.

These helpers simplify the process for consumer drivers (such as Ethernet
controllers or PHYs) to look up their associated DPLL pins defined in
the DT or ACPI, which can then be passed to the DPLL subsystem to acquire
the pin object.

I don't see cells defined in your binding. Neither updated property.c.
WDYM by property.c ?
Each standardized phandle reliationship is supposed to be reflected with
device links (at least of now... maybe it already changed after this LPC?)
