Three fixes for the zl3073x DPLL driver.

Patch 1 exports __dpll_device_change_ntf() for use by drivers that
need to send device change notifications from within callbacks
already running under dpll_lock.

Patch 2 replaces the change_work workqueue mechanism with direct
calls to __dpll_device_change_ntf(), eliminating a race condition
where the work handler could dereference a freed dpll_dev pointer
during device teardown.

Patch 3 moves the freq_monitor flag from per-DPLL to per-device
scope to match the hardware behavior where frequency measurement
registers are shared across all DPLL channels.

Ivan Vecera (3):
  dpll: export __dpll_device_change_ntf() for use under dpll_lock
  dpll: zl3073x: use __dpll_device_change_ntf() and remove change_work
  dpll: zl3073x: make frequency monitor a per-device attribute
