Both SM8550 and SM8650 misuse mdp1-mem interconnect path for the
LLCC->EBI path, while it should only be used for the MDP->EBI paths.
This kind of misuse can result in bandwidth underflows, possibly
degradating picture quality as the required memory bandwidth is divided
between all mdpN-mem paths (and LLCC-EBI should not be a part of such
division).
Drop mdp1-mem paths and use MDP-EBI path directly.
