Subject: [PATCH 6/9] arm64: dts: qcom: sdm845: Add "simple-bus" to our mdss node

As described in the bindings patch, this means that our child nodes
are devices in their own right.

Signed-off-by: Douglas Anderson <dianders@...omium.org>

If this patch lands before the patch ("drm/msm: Avoid manually
populating our children if "simple-bus" is there") it doesn't seem to
be the end of the world.  The first time through
add_display_components() it'll notice that the children are already
populated and it will be a no-op.  When it gets a defer it will then
depouplate them (even though it didn't populate them) and future calls
will just populate them again.
