Revert "ARM: dts: msm: remove sync-wait-broadcast from jdi panel"

This reverts commit c9b3e1eb ("ARM: dts:
msm: remove sync-wait-broadcast from jdi panel"). Sync-wait-broadcast
flag was removed for JDI dual dsi cmd mode panel as there were fps issues
when used along with partial updates which is currently fixed. The flag
is required for mode switch as sending the switch commands individually
during cmd-to-video switch causes flicker issues. Revert this change
to add the flag back as it is needed for mode switch.
