media: imx: imx7-media-csi: Remove incorrect interlacing support

Browse Source 
The driver doesn't currently support interlacing, but due to legacy
leftovers, it accepts values for the pixel format "field" field other
than V4L2_FIELD_NONE. Fix it by hardcoding V4L2_FIELD_NONE. Proper
interlacing support can be implemented later if desired.
