msm8996: Panels are not under mdss_mdp

[barni2000]

On msm8996 xiaomis panels are placed under soc node instead of mdss_mdp.

I cannot generate panel drivers without move panels under mdss_mdp node.

Update this function then? https://github.com/msm8916-mainline/linux-mdss-dsi-panel-driver-generator/blob/master/panel.py#L337
