Harigovindan P 8dd3b42c57 disp: msm: read mdp intf line count and trigger dma accordingly ...

when a broadcast DSI command is scheduled, the command can get
triggered close to the schedule line. This might cause DMA
timeout. This change reads the video line count from
MDP_INTF_LINE_COUNT register and checks whether DMA trigger
happens close to the schedule line. If it is not close to the
schedule line, then DMA command transfer is triggered.
