Do we have any pressing need to convert AMBA stuff?  I haven't heard any
reason yet to convert them to runtime PM - they don't even make any
runtime PM calls.

Maybe Linus can comment on the PM stuff as he has SoCs with these in.
As my boards don't have any sensible PM support, I don't have any
visibility of what PM facilities would be required.
