Subject: drm/bridge: Add stubs for devm_drm_of_get_bridge when OF is disabled
Git-commit: 59050d783848d9b62e9d8fb6ce0cd00771c2bf87
Patch-mainline: v5.16-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

If CONFIG_OF is disabled, devm_drm_of_get_bridge won't be compiled in
and drivers using that function will fail to build.

Add an inline stub so that we can still build-test those cases.
