CAL driver enumerates mbus codes in the connected subdev to create a list of supported formats reported to userspace, and initializes ctx->v_fmt and ctx->fmtinfo to one of those formats. This works fine for legacy mode, but is not correct for MC mode, and the list is not even used in MC mode. Fix this by adding a new function, cal_ctx_v4l2_init_mc_format, which only initializes ctx->v_fmt and ctx->fmtinfo to a default value.
