Move the bus clock to mdp device node,in order to facilitate bus band width scaling on sc7180 target.
The parent device MDSS will not vote for bus bw, instead the vote will be triggered by mdp device node. Since a minimum vote is required to turn on bus clock, move the clock node to mdp device from where the votes are requested.
This patch has dependency on the below series https://patchwork.kernel.org/patch/11468783/

Please be more specific about which interconnect entries are added. Also no need to repeat 'sc7180', it is already clear from the prefix.
