STOP mode for F7 is needed for wakeup from multiple EXTI pins. For example PD0, which is CAN rx.
However, for F40X & F42X this may be useless. STOP in itself eats more current than standby.
With F4 only having PA0 available for wakeup, this negates its need.

* Standby for both F4 & F7 works perfectly, with very little current consumption.
* Downside is that there is a limited amount of pins that can wakeup F7, and only PA0 for F4XX.
