Karl Palsson 095ed8511a stm32l1: rcc: reliably clock up/down ...

When changing the system clock, you must take care to not exceed the
legal ranges based on voltage and flash wait states.

Existing code made it possible to provide a valid clock structure, that
would run out of bounds temporarily.  Some boards would crash with
various Usage faults / Bus errors due to this.
