Add initial support for MLX90640 thermal cameras which output an 32x24

Because of this the data outputed is really 32x26 and needs the two rows

Hello everyone
when we need to setup media pipeline, eg, for camera capture, media-ctl
needs to be called multiple time to setup media link and subdev

Hi,
This series introduces the Media driver to work with the i.MX7 SoC. it uses the
already existing imx media core drivers but since the i.MX7, contrary to
i.MX5/6, do not have an IPU and because of that some changes in the imx media
core are made along this series to make it support that case.
