There is getting more entities to manage within single video pipeline in newer SoCs. To simplify code put subdevs' pointer into an array rather than adding new member in struct fimc_pipeline for each subdev. This allows to easier handle subdev operations in proper order. Additionally walk graph in one direction only in fimc_pipeline_prepare() function to make sure we properly gather only media entities that below to single data pipeline. This avoids wrong initialization in case where, for example there are multiple active links from s5p-mipi-csis subdev output pad. struct fimc_pipeline declaration is moved to the driver's public header to allow other drivers to reuse the fimc-lite driver added in subsequent patches.
