Damien George e3187b052f stm32/boards/PYBD: Change RTC asynch prediv from 1 to 4.
This change has the following effects:
- Reduces the resolution of the RTC sub-second counter from 30.52us to
  122.07us.
- Allows RTC.calibration() to now support positive values (as well as
  negative values).
- Reduces VBAT current consumption in standby mode by a small amount.

For general purpose use 122us resolution of the sub-second counter is
good enough, and the benefits of full range calibration and minor reduction
in VBAT consumption are worth the change.
