Revert "drm/i2c: adv7511: Move to bridge folder"

The latest kernel moved the adv7511 to drm bridge, and the adv7511
driver has been updated to align with latest DRM core such as atomic
modesetting. As it requires the major change in the DRM driver,
this reverts commit c582778900425d0cf2a5687a84b0125fee797d32
("drm/i2c: adv7511: Move to bridge folder") partially, in order to
revive the adv7511 encoder slave. This is a temporary solution to
enable the design.

The DRM driver needs to support the atomic modesetting as well as
the drm bridge. When those changes are in, this can be removed.
