The mtk-dpi driver still uses the drm_encoder API which is now somewhat
deprecated. We started to move all the Mediatek drivers to the drm_bridge API,
like we did for the mtk-dsi driver [1], this is another small step to be able to
fully convert the DRM Mediatek drivers to the drm_bridge API. A dummy
drm_encoder is maintained in the mtk-dpi driver but the end goal is move all the
dummy drm_encoder (mtk-dsi, mtk-dpi, etc) to the main mtk_drm_drv driver.
[1] https://lore.kernel.org/patchwork/project/lkml/list/?series=441559
Changes in v2:
- Maintain error message when attach to bridge fails. (Boris)
- Drop the third patch.

This is really a cosmetic change just to make a bit more readable the
code after convert the driver to drm_bridge. The bridge variable name
will be used by the encoder drm_bridge, and the chained bridge will be
named next_bridge.
