media: imx: add csc/scaler mem2mem device
Add a single imx-media mem2mem video device that uses the IPU IC PP
(image converter post processing) task for scaling and colorspace
conversion.
On i.MX6Q/DL SoCs with two IPUs currently only the first IPU is used.
The hardware only supports writing to destination buffers up to
1024x1024 pixels in a single pass, arbitrary sizes can be achieved
by rendering multiple tiles per frame.
[slongerbeam@gmail.com: use ipu_image_convert_adjust(), fix
device_run() error handling, add missing media-device header,
unregister and remove the mem2mem device in error paths in
imx_media_probe_complete() and in imx_media_remove(), updated
for sync subdev registration]
