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.

v4l2-pci-skeleton: Only build if PCI is available Currently arm64 does not support PCI but it does support v4l2. Since the PCI skeleton driver is built unconditionally as a module with no dependency on PCI this causes build failures for arm64 allmodconfig.

samples: move blackfin gptimers-example from Documentation Move blackfin gptimers-example to samples and remove it from Documentation Makefile. Update samples Kconfig and Makefile to build gptimers-example. blackfin is the last CONFIG_BUILD_DOCSRC target in Documentation/Makefile. Hence this patch also includes changes to remove CONFIG_BUILD_DOCSRC from Makefile and lib/Kconfig.debug and updates VIDEO_PCI_SKELETON dependency on BUILD_DOCSRC. Documentation/Makefile is not deleted to avoid braking make htmldocs and make distclean.

Instead of the OF API, use more generic fwnode API to obtain the same information. As the V4L2 fwnode support will be required by a small minority of e.g. ACPI based systems (the same might actually go for OF), make this a module instead of embedding it in the videodev module.
