[media] exynos4-is: Add Exynos4x12 FIMC-IS driver
This patch adds a set of core files of the Exynos4x12 FIMC-IS V4L2 driver. This includes main functionality like allocating memory, loading the firmware, FIMC-IS register interface and host CPU <-> IS command and error code definitions. The driver currently exposes a single subdev named FIMC-IS-ISP, which corresponds to the FIMC-IS ISP and DRC IP blocks. The FIMC-IS-ISP subdev currently supports only a subset of user controls. For other controls we need several extensions at the V4L2 API. The supported standard controls are: brightness, contrast, saturation, hue, sharpness, 3a_lock, exposure_time_absolute, white_balance_auto_preset, iso_sensitivity, iso_sensitivity_auto, exposure_metering_mode.
