msm: mdss: Handle ping pong split configuration in splash done

Browse source 
After continuous splash reconfiguration, when turning off the
clocks ping pong split configuration is not handled properly.
Pingpong split uses single controller and dual context, so
the second context of the same controller should be used
instead of the slave controller.
