drm/msm: Construct only one encoder for DSI
We currently create 2 encoders for DSI interfaces, one for command mode and other for video mode operation. This isn't needed as we can't really use both the encoders at the same time. It also makes connecting bridges harder. Switch to creating a single encoder. For now, we assume that the encoder is configured only in video mode. Later, the same encoder would be usable in both modes. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
