media: videobuf2: Add VIDEOBUF2_V4L2 Kconfig option for VB2 V4L2 part Videobuf2 is now separate from V4L2 and can be now built without it, at least in principle --- enabling videobuf2 in kernel configuration attempts to compile videobuf2-v4l2.c but that will fail if CONFIG_VIDEO_V4L2 isn't enabled. Solve this by adding a separate Kconfig option for videobuf2-v4l2 and make it a separate module as well. This means that drivers now need to choose both the appropriate videobuf2 memory type (VIDEOBUF2_{VMALLOC,DMA_CONTIG,DMA_SG}) and VIDEOBUF2_V4L2 if they need both.

media: add v4l2 JPEG helpers Add helpers for JPEG header parsing. They allow both scanning for marker segment positions and later parsing the segments individually, as required by s5p-jpeg, as well as parsing all headers in one go, as required by coda-vpu. The frame header is always parsed, as basically all decoders are interested in width, height, and number of components. For convenience, the JPEG chroma subsampling factors are decoded into a v4l2_jpeg_chroma_subsampling enum. Only baseline and extended sequential DCT encoded JPEGs with 8-bit or 12-bit precision with up to four components are supported.
