Enables MST for the sa8775p platform by setting `max_stream = 4`. Platform enablement patch.

---

**Summary of required fixes before merge**:
1. **Patch 30**: `IS_ERR(dp->panel)` → `IS_ERR(dp_panel)` (crash bug)
2. **Patch 34**: Use `drm_atomic_get_mst_topology_state(state, &mst->mst_mgr)` instead of `to_drm_dp_mst_topology_state(mst->mst_mgr.base.state)` in `atomic_check` (correctness/races)
3. **Patch 01**: Free the `drm_edid` after `drm_edid_connector_update()` (memory leak)
4. **Patch 34**: Check return value of `drm_dp_atomic_find_time_slots()` for errors
