media: camss: vfe: Format conversion support using PIX interface
Use VFE PIX input interface and do format conversion in VFE.
Supported input format is UYVY (single plane YUV 4:2:2) and
its different sample order variations.
Supported output formats are:
- NV12/NV21 (two plane YUV 4:2:0)
- NV16/NV61 (two plane YUV 4:2:2)
