msm: mdss: send col_page dcs command when frame size changed

Browse source 
When partial update and sync-wait-broadcast enable, col_page
address dcs command are sent to panel on every frame update
which generates unnecessary interrupts and cause frame rate
to dropped. To avoid unnecessary interrupts, col_page address
dcs commands are sent only when frame size changed. Since
sync-wait-broadcast enabled, col_page address of both
left and right dsi controller need to be sent at same
trigger.
