[PATCH v3 01/11] include: linux: Add C3 ISP Stats and Params V4L2 format

[Keke Li]

Add the new format describing the C3 ISP Statistics and Parameters
to videodev2. These come from the v6 of the C3 ISP kernel driver
series[1]. Once the kernel driver is merged we can replace these
temporary manual additions with updates to the scripts that merge
in the kernel headers.
