If this driver requires this API then it should select VIDEO_V4L2_SUBDEV_API.
Could you eventually send a bug report upstream?

CONFIG_VIDEO_V4L2_SUBDEV_API was available in Linux 6.3 thanks to the 
CONFIG_VIDEO_NOON010PC30 option. However that camera sensor driver has been
dropped in Linux 6.4 and none of the camera sensor drivers enabled in Debian
select CONFIG_VIDEO_V4L2_SUBDEV_API.

Understandable ;)
