Why don't we have runtime_pm on Ivybridge since we have on
sandybdrige? Imre, any idea?

This patch made me notice that we should define the
GEN7_FEATURE on GEN6_FEATURES + new changes as a followup of patch
02/32 or in that same patch.
However for this case we should redefine .has_runtime_pm=0 on gen7,
what is really strange.
Anyway, this patch itself has nothing wrong and just follows what it
was set there already.
any change related to my comments should be addressed in separated patches.
So fell free to also use
