[PATCH v4 13/27] rcar-vin: do not cut height in two for top, bottom or alternate fields

[Niklas Söderlund]

The height should not be cut in half for the format for top, bottom or
alternate fields settings. This was a mistake and it was made
visible by the scaling refactoring.

Correct behavior is that the user should request a frame size that fits
the half height frame reflected in the field setting. If not the VIN
will do it's best to scale the top or bottom to the requested format and
cropping and scaling do not work as expected.
