Historia
robert-hh b70b8ce3e4 mimxrt/machine_rtc: Start RTC at boot and set datetime if not set. 
Changes in this commit:
- Start the RTC Timer at system boot.  Otherwise time.time() will advance
  only if an RTC() object was created.
- Set the time to a more recent date than Jan 1, 1970, if not set.  That is
  2013/10/14, 19:53:11, MicroPython's first commit.
- Compensate an underflow in in timeutils_seconds_since_2000(), called by
  time.time(), if the time is set to a pre-2000 date.
