drm/i2c: move TDA998x driver under drivers/gpu/drm/bridge

TDA998x is the HDMI bridge driver, incorporating drm_connector and
optional drm_encoder (created via the component bind API by the TICLDC
and HDLCD drivers). Thus it should be residing together with the other
DRM bridge drivers under drivers/gpu/drm/bridge/.
