Switch DPU from dsi-staging to upstream dsi driver. To make the switch atomic, this change includes: - remove dpu connector layers - clean up dpu connector dependencies in encoder/crtc - compile out writeback and display port drivers - compile out dsi-staging driver (separate patch submitted to remove the driver) - adapt upstream device hierarchy

changes in v2: - remove files not applicable upstream (Sean Paul) - remove compiled out non-dsi display init (Sean Paul) - split unrelated changes into separate patch set (Sean Paul)
