Subject: [PATCH] v4l2_calls: define V4L2_CID_HCENTER and V4L2_CID_VCENTER

kernel commit 24b9f5017 [[media] V4L: Remove deprecated image centering controls]
removed the definitions of V4L2_CID_HCENTER and V4L2_CID_VCENTER after three
years of depreciation.

The ioctl values are still free, and the case statement which processess them
in v4l2 userspace falls through to the proper replacement. So in the short
term, we can explicitly define them using the old absolute values, and everything
will work.
