Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next

On the userspace side, all the basics are working, and most of glmark2
is working.  I've been working through deqp, and I've got a couple more
things to fix (but we've gone from 70% to 80+% pass in last day, and
current deqp run that is going should pick up another 5-10%).  I expect
to push the mesa patches today or tomorrow.

There are a couple more a5xx related patches to take the gpu out of
secure mode (for the devices that come up in secure mode, like the hw
I have), but those depend on an scm patch that would come in through
another tree.  If that can land in the next day or two, there might
be a second late pull request for drm/msm.

In addition to the new-shiny, there have also been a lot of overlay/
plane related fixes for issues found using drm-hwc2 (in the process of
testing/debugging the atomic/kms fence patches), resulting in rework
to assign hwpipes to kms planes dynamically (as part of global atomic
state) and also handling SMP (fifo) block allocation atomically as
part of the ->atomic_check() step.  All those patches should also help
out atomic weston (when those patches eventually land).
