drivers: clock_control_nrf2_common: Add resetting of the on-off services

If an on-off service records an error while transitioning to the on
state, it stays in the error state and does not allow new requests
to be made until its state is reset. Add resetting of the services
associated with particular clock controllers so that requests can
be retried after failures.
