Add static qualifier for of_display_mode_bridge_funcs to resolve the
sparse warning:
drivers/gpu/drm/bridge/of-display-mode-bridge.c:54:25: sparse: sparse:
symbol 'of_display_mode_bridge_funcs' was not declared. Should it be
static?
Also mark the structure const as required by devm_drm_bridge_alloc()
parameter type constraints.
Fixes: ba2db93cf3d5 ("drm/bridge: Move legacy bridge driver out of imx directory for multi-platform use")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202606170744.FUStcWaB-lkp@intel.com/
