This fixes the warnings like
"plane A assertion failure, should be disabled but not"
that on the initial modeset during boot. This can happen if
the primary plane is enabled by the firmware, but inheriting
it fails because the DMAR is active or for other reasons.
Most likely caused by

On skylake and broxton the old registers are no longer in use.
Instead it uses universal planes, fix primary_get_hw to use the
correct registers.

SKL/BXT have only preliminary support in v4.2, so I'm not queuing
SKL/BXT specific fixes there. v4.3 is another matter.

Why did the commit message not explain that this was a forward port?
</broken-maintainer-record>
Anyway we still seem to have a bit of a mess in the plane reconstruction
code - if intel_find_initial_plane_obj fails we don't shut down the plane,
but an enabled plane without an fb attached will upset the drm core a bit
...
Anyway applied this to dinq (with the forward-port note attached).

Maarten, this patch has no reviews and it no longer applies to v4.3
cleanly. Please rebase and repost if it's still valid.
