This is of course an ABI breakage that affects Linux kernels starting
with 4.13 and up to 4.18, as well as their LTS derivatives.

Since the imx driver didn't provide any public control ID definitions,
it looks like the best way to handle this situation is to pretend that
the old value of V4L2_CID_USER_IMX_BASE didn't exist.

* xlat/v4l2_control_id_bases.in (V4L2_CID_USER_IMX_BASE): Redefine.
