drm: mali-dp: Add writeback connector
Mali-DP has a memory writeback engine which can be used to write the
composition result to a memory buffer. Expose this functionality as a
DRM writeback connector on supported hardware.
Changes since v1:
Daniel Vetter:
- Don't require a modeset when writeback routing changes
- Make writeback connector always disconnected
Changes since v2:
- Rebase onto new drm_writeback_connector
- Add reset callback, allocating subclassed state
Daniel Vetter:
- Squash out-fence support into this commit
Gustavo Padovan:
- Don't signal fence directly from driver (and drop malidp_mw_job)
Changes since v3:
- Modifications to fit with Mali-DP commit tail changes
