Add cwb dither support. Catalog: Read dtsi value of cwb dither in pp parse part. Wb: Install blob property for cwb dither. Wb hw: Adds a new wb ops function to program cwb dither hardware. CRTC: To ensure that userspace can check whether cwb dither is supported, added "has_cwb_dither" to sde kms info. PingPong: In order to reuse dither's map array, move dither_depth_map array to pp header file. Change-Id: I77e6a052a00b7c649452103145e5d7b4c8deb3a2 Signed-off-by: Yuchao Ma <yuchaom@codeaurora.org>
