[Intel-gfx] [BUG] i915: suspend by closing Laptop lid broken

[Martin Kepplinger]

So. -rc1 broke suspending by closing my laptop lid and it's not fixed in
-rc2. It works exactly *one* first time and every subsequent lid-closing
is ignored.

Biscted and tested first bad commit:

This pulls in i915 changes as well as ACPI changes. I don't know the
driver but I'm sure you can find the mistake. I'm happy to test changes.

There are no log differences.
