[ Upstream commit 3d3f7c1e68691574c1d87cd0f9f2348323bc0199 ]
Add a function to find a connector based on a fwnode.
This will be used by the new drm_connector_oob_hotplug_event()
function which is added by the next patch in this patch-set.
Changes in v2:
- Complete rewrite to use a global connector list in drm_connector.c
rather then using a class-dev-iter in drm_sysfs.c
Changes in v3:
- Add forward declaration for struct fwnode_handle to drm_crtc_internal.h
