arm64: dts: qcom: sm8550: add missing cpu-cfg interconnect path in the mdss node

Browse Source 
The bindings requires the mdp0-mem and the cpu-cfg interconnect path,
add the missing cpu-cfg path to fix the dtbs check error and also to ensure
that MDSS has enough bandwidth to let HLOS write config registers.
