When clock get_rate() is called, return by default the calibrated frequency instead of nominal one. This improves accuracy specially when internal RC SLOW clock is used. To guarantee that nominal values can be still be retrieved, add a new type of clock subsys for such scenario. west.yml is also updated to add fix into calibration sources.
