Subject: [PATCH] ice: dpll: fix initial lock status of dpll
When dpll device is registered and dpll subsystem performs notify of a
new device, the lock state value provided to dpll subsystem equals 0
which is invalid value for the `enum dpll_lock_status`.
Provide correct value by obtaining it from firmware before registering
the dpll device.
Fixes: d7999f5ea64b ("ice: implement dpll interface to control cgu")
