We have new tests and fixes in place since the feature was last
disabled. Try again for gen-9+ hardware and enable only PSR1 by default as
a first step.
v2: Remove typo fix and comment improvements (Rodrigo)

It seems that we still need to wait and check why shard-skl wasn't up on this CI,
but patch itself is right, so
