drm/bridge: add of_drm_find_and_get_bridge()
of_drm_find_bridge() does not increment the refcount for the returned
bridge, but that is required now. However converting it and all its users
is not realistically doable at once given the large amount of (direct and
indirect) callers and the complexity of some.
Solve this issue by creating a new of_drm_find_and_get_bridge() function
that is identical to of_drm_find_bridge() except also it takes a
reference. Then of_drm_find_bridge() will be deprecated to be eventually
removed.
