Harald Welte 5e00400a05 board_lowlevel.c: Improve main oscillator initialization ...

* ensure the PB8/PB9 pins are actually not in GPIO mode, which they
  apparently are on boot-up
* ensure that neither pull-up nor pull-down are enabled on PB8/PB9
* ensure we first start the oscillator, before selecting it

The sum of the above changes seems to make oscillator start-up much more
reliable than before.  The time needed for initialization is now pretty
stable, and the occasional 15-20second clock stabiliziation has not been
observed with this change.
