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)
