Add sm8150/sm8250 compatibles to drm/msm and fix the sm8250
display nodes.

The driver already has support for sm8150/sm8250, but the compatibles were
never added.

Also inverse the non-mdp4 condition in add_display_components() to avoid
having to check every new compatible in the condition.

These two chunks should probably go to the separate patch 'dt-bindings:...'.

Also, could you please pinpoint the reason for adding more
compatibility strings, while they map to the same internal data?
I think we might want instead to use some generic name for the dpu
block, like "qcom,dpu" or "qcom,mdp-dpu" instead of specifying the
platform name.

In this case I think its better to have this change in the same patch, 
but maybe one of the Robs will disagree.

sdm845 and sc7180 aren't using generic compatibles, this is just being 
consistent with that.

Well, I suppose the common case is to use the 'first compatible' entry
if the entities are compatible. The generic compatibles is a proposal,
not an affirmation. Please excuse me if it sounded in a different way.

I *think* typically the reason to split dt bindings into their own
patch is that devicetree@ list isn't interested in reviewing driver
changes, just binding changes..

In this case since it is just adding a compatible I think it is ok..
(or at least ok by me, but maybe other-Rob disagrees ;-))

It is good to have a device specific compatible up front, even if we
fallback to the more generic one for matching.. just in case we find a
reason for needing it later
