[media] s5p-fimc: Add support for V4L2_PIX_FMT_S5C_UYVY_JPG fourcc
The V4L2_PIX_FMT_S5C_YUYV_JPG image formats consists of 2 planes, the first containing interleaved JPEG/YUYV data and the second containing meta data describing the interleaving method. The image data is transferred with MIPI-CSI "User Defined Byte-Based Data 1" type and is captured to memory by FIMC DMA engine. The meta data is transferred using MIPI-CSI2 "Embedded 8-bit non Image Data" and it is captured in the MIPI-CSI slave device and copied to the bridge provided buffer. To make sure the size of allocated buffers is correct for the subdevs configuration when VIDIOC_STREAMON ioctl is invoked, an additional check is added at the video pipeline validation function. Flag FMT_FLAGS_COMPRESSED indicates the buffer size must be retrieved from a sensor subdev.
