drivers: npcx: convert NPCX drivers clock client to DEVICE_DT_GET
Convert the various device_get_binding() calls used to get the device clock node to use DEVICE_DT_GET. The latter is processed at link time, so it should be a bit more efficient. Signed-off-by: Fabio Baltieri <fabiobaltieri@google.com>
