The only difference compared to v1 is [4/6] which I left un-squashed
to ease review.

The issue is subtle and manifests itself with a number of CTS tests
that "fail to open camera". The culprit is the ov13858 minimum frame
duration that is registered as 33389 microseconds, and the android
camera framework filters away all streams intended for preview/record
with a minimum frame duration larger than 33366 microseconds.

The rounding criteria are quite arbitrary, so I expect someone to
scream to those.

Thanks
