[PULL] topic/pipe-reorder for drm-intel-next and possibly v7.1-rc1

[Jani Nikula <jani.nikula@intel.com>]

Hi Dave & Linus -

This is a topic pull request for changing the pipe allocation order for
discrete platforms from the usual A,B,C,D to A,C,B,D. The goal is to
help pipe joiner configurations that reserve the adjacent pipe as the
secondary pipe without the user space knowing. More details in the
relevant commit message. The CRTC iteration is also changed to remain in
pipe order.

This has been a long time in the making, primarily because IGT basically
assumed CRTC index == pipe, and it took hundreds of commits from Ville
and me over several months to untangle it, and actually get CI results.

I'm going to merge this to drm-intel-next soon, and at this point in
time it would normally target v7.2.

We're fully aware this is beyond feature deadlines for v7.1 and it
hasn't seen linux-next. But in the off-chance you might consider also
pulling this as a fix for v7.1 (and really, distros might want this to
be backported to stable) I'm sending this as a separate topic pull
request.

I'm leaving it to your discretion.

BR,
Jani.
