Merge tag 'drm-msm-next-2018-08-10' of git://people.freedesktop.org/~robclark/linux...

An optional follow-on PR for 4.19, on top of previous -fixes PR, which
brings in a6xx support.

These patches have been on list since earlier in the year (mostly
waiting for userspace).  They have been in linux-next since earlier in
the week, now that we have freedreno userspace working on a6xx[1][2].
So far glmark2, Chromium/ChromiumOS, gnome-shell, glamor, xonotic,
etc, are working.  And a healthy chuck of deqp works, and I've been
busy fixing things.  The needed libdrm changes (no new uapi changes
needed) are already on master, and the 2nd branch is rebased on that.
