I think we don't need the full set of tests also with system suspend. I
think just one test which catches the current bug is good enough, after
all if psr is set up correctly it should work the same at runtime than
over s/r. And since this is a test I'd just copypaste the relevant subtest
(if it doesn't integrate quickly into the existing code), not worth at all
to make a big fuzz.
And we have lots of resume tests already, they "only" take about
30 second. Only important to have "suspend" somewhere in the subtest name
so that all system suspend tests can easily be filtered out/selected.
