No need for local struct drm_device * since dev_priv is the
correct thing to pass in to NEEDS_WaRsDisableCoarsePowerGating
anyway. Changed the macro definition for the latter to reflect
that as well.

Just wondering if you fancy having a go at IS_SKL_GT(dev_priv, min, max)...

What do you have in mind?

This is a single call site for them BTW. And GCC amazingly does manage to merge the two GT tests on its own already. :)
