Wayne Lin 580aa2782c drm/dp_mst: Add helper to get port number at specific LCT from RAD
Add a helper drm_dp_mst_get_ufp_num_at_lct_from_rad() to extract the up
facing port number at specific link count from the RAD. Use the added
helper in drm_dp_mst_rad_to_str() & drm_dp_get_mst_branch_device() to
unify the implementation.

V2:
- Adjust the code format (Lyude)

V3:
- Adjust parameter "rad" of drm_dp_mst_get_ufp_num_at_lct_from_rad() to
be constant (Kernel test robot)
