[v2,0/4] Update AUX invalidation sequence

Message

Hi,

as there are new hardware directives, we need a little adaptation
for the AUX invalidation sequence.

In this version we support all the engines affected by this
change.

The stable backport has some challenges because the original
patch that this series fixes has had more changes in between.

Thanks,
Andi
