drm/i915: Start using comparative INTEL_PCH_TYPE
In order to make it easier to bring up new platforms
without having to take care about all corner cases
that was previously taken care for previous platforms
we already use comparative INTEL_GEN statements.
Let's start doing the same with PCH.
The only caveats are:
- less-than comparisons need to be avoided or done with
attention and check > PCH_NONE as well.
- It is not necessarily a chronological order, but a matter
of south display compatibility/inheritance.
v2: Rebased on top of Jani's clean-up which removed the
need for less-than comparison
