With only a couple of exceptions (BSD user interrupt) there is no need
for per-gen values. I think we shouldn't have much trouble maintaining
this as is. The existing naming scheme wrongly calls things GEN6 when
they were introduced earlier (I'm also not sure GT_ is valid for every
interrupt). So the goal was to have I915_* for old stuff, INTEL_* for
everything, and DEVICENAME_ for special cases.
