Writeback uses the WB_PICTURE_SIZE register to define the size of the content
written to memory, this is the output of the scalar. It uses the WB_SIZE
register to define the size of the content coming from the overlay/manager to
which it is connected, this is the input to the scalar. This naming is different
as compared to overlays.

Add checks for writeback in dispc_plane_set_input_size() and
dispc_plane_set_output_size() to write to the correct registers.
