Subject: [Intel-wired-lan] [PATCH net-next v3 6/9] dpll: Enhance and
consolidate reference counting logic

Refactor the reference counting mechanism for DPLL devices and pins to
improve consistency and prevent potential lifetime issues.

Introduce internal helpers __dpll_{device,pin}_{hold,put}() to
centralize reference management.

Update the internal XArray reference helpers (dpll_xa_ref_*) to
automatically grab a reference to the target object when it is added
to a list, and release it when removed. This ensures that objects
linked internally (e.g., pins referenced by parent pins) are properly
kept alive without relying on the caller to manually manage the count.

Consequently, remove the now redundant manual `refcount_inc/dec` calls
in dpll_pin_on_pin_{,un}register()`, as ownership is now correctly
handled by the dpll_xa_ref_* functions.

Additionally, ensure that dpll_device_{,un}register()` takes/releases
a reference to the device, ensuring the device object remains valid
for the duration of its registration.
