include: linux: Update headers for line-based embedded data support

Browse source 
Update the kernel headers with the definition of two device-specific
line-based metadata formats, and with the definition of the
MEDIA_PAD_FL_INTERNAL and V4L2_SUBDEV_ROUTE_FL_IMMUTABLE flags.

The new definitions will allow to support handling line-based
metadata streams exposed by the sensor driver through an
internal sink pad.

While the changes have not yet been collected in the official
linux-media tree, they're available in the 'metadata' branch of
https://git.linuxtv.org/sailus/media_tree.git, at revision:
f9bbbd9a696d ("media: Documentation: Add binning and sub-sampling
controls")
