dpll: export __dpll_device_change_ntf() for use under dpll_lock

Export __dpll_device_change_ntf() so that drivers can send device
change notifications from within device callbacks, which are already
called under dpll_lock. Using dpll_device_change_ntf() in that
context would deadlock.

Add lockdep_assert_held() to catch misuse without the lock held.
