drm/crtc-helper: Transitional functions using atomic plane helpers
These two functions allow drivers to reuse their atomic plane helpers functions for the primary plane to implement the interfaces required by the crtc helpers for the legacy ->set_config callback. This is purely transitional and won't be used once the driver is fully converted. But it allows partial conversions to the atomic plane helpers which are functional. v2: - Use ->atomic_duplicate_state if available. - Don't forget to run crtc_funcs->atomic_check. v3: Shift source coordinates correctly for 16.16 fixed point. v4: Don't forget to call ->atomic_destroy_state if available. v5: Fixup kerneldoc. v6: Reuse the plane_commit function from the transitional plane helpers to avoid too much duplication. v7: - Remove some stale comment. - Correctly handle the lack of plane->state object, necessary for transitional use. v8: Fixup an embarrassing h/vdisplay mixup.
