HD panel (1366x768) found most commonly on laptops can't be represented
exactly in CVT/DMT expression, which leads to 1368x768 instead, because

Spurred by an irc discussion, let's start to clear up which parts of
our kms + ums/gem + ums/dri1 + vbios/dri1 kernel driver pieces
userspace in the wild actually uses.

The idea is that we introduce checks at entry-points (module load
time, ioctls, ...) first and then reap any obviously dead code in a
second step.

As a first step refuse to load without kms on chips where userspace
never supported ums. Now upstream hasn't supported ums on ilk, ever.
But RHEL had the great idea to backport the kms support to their ums
driver.

vlv, ivb and snb all share the gen6+ gt irq handling. 3 copies of the
same stuff is a bit much, so extract it into a little helper.

Now ilk has a different gt irq handling than snb, but shares the same
irq handler (due to the similar display block). So also extract the
ilk gt irq handling to clearly separate these two things.

Nice side effect of this is that we can complete Ben Widawsky's gen6+
irq bit #define cleanup and call the render irq also with the GEN6
alias. Beforehand that code was shared with ilk, and neither option
really made much sense.

As a bonus this enables the error interrupt handling lifted from the
vlv code on snb and ivb, too.

Top-level interrupt bits are usually found in the display block. It
therefore makes sense to use HAS_PCH_SPLIT in i915_irq.c

But the irq stuff in intel_ring.c only concerns itself with render
core/gt-level interrupt sources. It therefore makes more sense to
switch based on gpu gen.

Kills a vlv special case.

We can now open-code the get/put irq functions as they were just
abstracting single register definitions.

It would be nice to merge this in with the IRQ handling code... but that
is too much work for me at present. In addition I could probably
collapse this in to a lot of the Ironlake stuff, but I don't think it's
worth the potential regressions.

This patch itself should not effect functionality.
