drm/msm/sde: add sui blendstage and QoS FL caps for kona

Remove the HW check in post caps and add secure-ui
blendstage and QoS no calc fill-level as capabilities
that can be used later to update the relevant blocks.
This will consolidate all the target specific capabilities
to one place. On top of it add both the capabilities for
Kona target.
