[PATCH v1] drm/bridge: of-display-mode-bridge: Fix missing static const for the bridge funcs

[Damon Ding <damon.ding@rock-chips.com>]

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")
