ARM: dts: msm: Remove sync-wait-broadcast for NT35597 DDIC

When sync-wait-broadcast is enabled, panel status is read on both the
controllers. But for NT35597 DDIC, correct response is sent only on the
master controller. Thus, disabling sync-wait-broadcast to avoid reading on
slave controller for this DDIC for msm8998 and sdm660.
