stm32/powerctrlboot: Fix config of systick IRQ priority on F0/L0/WB MCU.

Browse Source 
Prior to this commit the systick IRQ priority was set at lowest priority on
F0/L0/WB MCUs, because it was left at the default and never configured.
This commit ensures the priority is configured and sets it to the highest
priority.
