[Intel-gfx] [RFC 0/3] Display uncore

[Daniele Ceraolo Spurio]

I've been trying to identify MMIO ranges to clearly define what belongs
to display_uncore to do a check on access, but there are lots of
exceptions and differences across gens (with a few more coming with TGL),
so I don't think that's a viable way. The alternative option implemented
here is to differentiate the register by type, which should ensure we
never mix them up, but at the cost of a more complex transition.

Thoughts? I'm very open to (and I actually hope for) better ideas.
