Subject: [PATCH RFC net-next 04/13] dpll: zl3073x: register pins with fwnode handle

Pass the firmware node handle to dpll_pin_get() when registering pins
in the zl3073x driver.

This allows the DPLL core to associate the created pin object with its
corresponding firmware node. Consequently, this enables consumer
drivers (such as network drivers) to locate and request this specific
pin using the fwnode_dpll_pin_find() helper.
