drivers: Add support for DPLL reference count tracking

drivers: Add support for DPLL reference count tracking

Update existing DPLL drivers to utilize the DPLL reference count
tracking infrastructure.

Add dpll_tracker fields to the drivers' internal device and pin
structures. Pass pointers to these trackers when calling
dpll_device_get/put() and dpll_pin_get/put().

This allows developers to inspect the specific references held by this
driver via debugfs when CONFIG_DPLL_REFCNT_TRACKER is enabled, aiding
in the debugging of resource leaks.
