Huh, right, those drivers shouldn't be relying on the phy.h to include
pm_runtime.h.

The easiest way at this point is to just put back "#include
<linux/pm_runtime.h>" in phy.h, then we can deal with these problems
separately. I do that in a re-spin soon.

BTW, I would be great if you could test this on the Renesas SoC to
make sure it still fixes the problems (at least half of them I mean).

Thanks and kind regards
Uffe
