Am I wrong or BIT() is not available to userspace ?

../../include/linux/v4l2-subdev.h:209:38: error: ‘BIT’ was not declared in this scope
   209 | #define V4L2_SUBDEV_ROUTE_FL_ACTIVE  BIT(0)

Header was exported with headers_install.

Yes, I think you are correct. I see only two other BIT() uses in uapi 
headers, and those might be errors too.
