Hm, I think we here either enter DC5 and right afterwards enter/exit
DC9, or enter/exit DC9 directly without entering DC5 at all. In any case
the DC9 entry/exit will zero the DC5/6 counters.

Based on this to be able to test DC5 alone we'd have to save/restore the
DC5/6 counters somehow across runtime suspend/resume, or just run the
test with runtime PM disabled (which prevents DC9).

There could be a related problem on platforms with both DC5 and 6 (ICL+)
in that we may skip DC5 if DC6 is allowed (and always just enter DC6 or
DC9). So this needs to be tested on such platforms.

This could be a problem where some other peripheral (SSD, network)
prevents DC6, so we need to configure those properly or (if that's not
possible for some reason) have some way to automatically skip the test
on such configs.

Do you have results for these tests that you ran on your own? Here I
can only see results for the DPMS tests not the PSR ones and only on
GLK/APL/KBL, as the tests were only run in shards that has only these
machines and wihtout any PSR panels.
