msm: mdss: remove wait for ping pong done for video interfaces

Wait for ping pong was used to ensure that hw is idle while programming
any double buffered registers, however most registers that really are
changing are double buffered. Remove for ping pong done as it's only
causing frame drops and some freezes in some cases.
