drm/bridge: ti-sn65dsi83: Replace connector format patching with atomic_get_input_bus_fmts
Patching the connector format is causing various problematic
side effects. Implement .atomic_get_input_bus_fmts callback
instead, which sets up the input (DSI-end) format, and that
format can then be used in pipeline format negotiation between
the DSI-end of this bridge and the other component closer to
the scanout engine.
