Merge #562
562: Replace default WFI with simpler NOP r=korken89 a=AfoHT
As noted by #561 there are multiple issues with various hardware implementations and debugging together with sleep modes.
As RTIC strives to be a generic framework (even though this is an implementation targeting cortex-m) the decision having `WFI` as the default `idle` task causes issues in some hardware, raising the barrier to entry.
This changes the default behaviour to do a simple `NOP` instead, adding documentation how to provide a custom `idle` task achieving the old default behaviour. Also removes the automatic setting of SLEEPONEXIT bit when no `idle` was provided, delegating this to the user.
This was discussed on the weekly meeting 2021-12-14 and this was the favoured solution.
Fixes #561
