9e4812771b stm32/powerctrl: Fix configuring APB1/APB2 frequency when AHB also set. 
APB1/APB2 are derived from AHB, so if the user sets AHB!=SYSCLK then the
APB1/APB2 dividers must be computed from the new AHB.

dff14c740b stm32/powerctrl: Move function to set SYSCLK into new powerctrl file. 
Power and clock control is low-level functionality and it makes sense to
have it in a dedicated file, at least so it can be reused by other parts of
the code.
