Merge branch 'drm_bridge_for_4.8' of https://github.com/boddob/linux into drm-next

This is an update to the previous drm bridge pull request. The ADV7511
driver's conversion from slave encoder to bridge meant that its users
(the rcar-du kms driver) should use the bridge interface too. This pull
request now also contains a commit that updates the rcar-du's hdmi encoder
interface from slave encoder to bridge.

The other updates are as before:

- Converts the ADV7511 i2c slave encoder driver to a bridge driver.
  Adds support for the ADV7533 bridge chip.
- Add bridge driver for TC358767 (DSI/DPI to eDP) encoder chips.
