Move the bus clock to mdp device node,in order to facilitate bus band width scaling on sm8250 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 commit message makes sense for the other commit, where you move the "bus" into the mdp. Do you mind me changing this to:
The bus clock is voted by the DPU, so remove it from the MDSS node.
I don't mind, please update the commit message as you see fit.
