stm32: Unify enable_pclock() code
Unify the handling of the enable_pclock() and is_enabled_pclock() code
across all stm32 chips. All chips will now perform a peripheral reset
on enable_pclock() (this is a change for stm32f0 and stm32h7). The
enable_pclock() code will now also disable irqs during the enable.
