In addition to the feedback I gave on v2, please also remove one of the

good to me, and then putting the node in alphabetical order.

I'm also curious about the power domain for DP. My guess is that both
DSI and DP nodes should be a child of mdss if they're in the display
subsystem and powered down/inaccessible when the mdss_gdsc is disabled.
