Fix the error of implicit declaration of function 'drmm_of_get_bridge':

drivers/gpu/drm/vc4/vc4_dpi.c:278:11: error: implicit declaration of function ‘drmm_of_get_bridge’; did you mean ‘devm_drm_of_get_bridge’? [-Werror=implicit-function-declaration]
  bridge = drmm_of_get_bridge(drm, dev->of_node, 0, 0);

Fixes: 055af0235aef ("drm/vc4: dpi: Switch to drmm_of_get_bridge")
