msm: mdss: Acquire lock for source format b/w line and block mode Currently there is a page fault and flicker while programming DMA pipe registers in Line mode. To prevent this acquire wb_lock between writeback kickoff (N-Cycle) and rotator setup(N+1 Cycle). wb_lock avoid rotator to update the pipe structure before writeback is finished programming to the hardware.
