struct drm_bridge already has a pointer to an encoder, can't you reuse
that instead?

Typically you'd embed the bridge into the driver structure.
I'm almost done with all the modifications according to your comments.
Remaining this point I can not understand, the dsi is a pointer of
drm_bridge,
hence I can not get the bridge by container_of.
Although, the "bridge->driver_private = dsi" have done in
dw_mipi_dsi_register.
