Downstream driver uses dpu->caps->smart_dma_rev to update

version. Upstream driver does not do this, resulting in SSPP subdriver

feature bits to dpu hw catalog.
While reviewing this patch, I had a first hand experience of how we
are reusing SSPP bitmasks for so many chipsets but I think overall
you got them right here :)

VIG_SDM845_MASK and DMA_SDM845_MASK are used for many other chipsets
like 8250, 8450, 8550.
At the moment, for visual validation of this series, I only have
sc7180/sc7280. We are leaving the rest for CI.
Was that an intentional approach?
If so, we will need tested-by tags from folks having
8350/8450/8550/sc8280x,qcm2290?
I am only owning the visual validation on sc7280 atm.
I'm not quite sure what is your intent here. Are there any SoCs after
845 that do not have SmartDMA 2.5? Or do you propose to enable
SmartDMA only for the chipsets that we can visually test? That sounds
strange.
Yes I was thinking to enable smartDMA at the moment on chipsets which we
can validate visually that display comes up. But I am not sure if thats
entirely practical.
But the intent was I just want to make sure basic display does come up
with smartDMA enabled if we are enabling it for all chipsets.
I don't think it is practical or logical. We don't require validating
other changes on all possible chipsets, so what is so different with
this one?
