[PATCH 0/4] Fix SKL runtime PM

[Paulo Zanoni <paulo.r.zanoni@intel.com>]

Hello

So I discovered that SKL runtime PM doesn't work on drm-intel-nightly and
decided to investigate why. I found this patch in one of Damien's trees and it
fixed the problem I was seeing. I really don't know why the patches were not
sent to the list yet and I can't ask him since he's on vacation. So I decided to
review them, implement my own bikesheds, add R-B tags and submit to the list,
since it's an important feature that's broken and preliminary_hw_support was
removed for SKL.

I hope the reason he didn't submit this is not because there's some bug I failed
to spot. Anyway, he'll tell us in a few days :).

Also notice that we're not passing every pm_rpm subtest now: we're just not
failing 100% of the tests.

Thanks,
Paulo
