[media] v4l2-dv-timings: support interlaced in v4l2_print_dv_timings

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

The v4l2_print_dv_timings() didn't log the interlaced format correctly. The timings
for the bottom field weren't logged and the fields per second value was half of what
it should have been.
