Problem
A wakeup source's interrupt priority is increased and never restored if it is duplicated in the wakeup source list or shares the same IRQ with other wakeup sources. Especially on Gen3, for critical SoftDevice region, a user application interrupt that would result in an error in SoftDevice.
Solution
Bump a wakeup source's interrupt priority only if it hasn't been bumped previously.
