What would that ioctl do?

You could add an ioctl func ptr to struct dvb_frontend_ops, and
call it (when !NULL) from dvb_frontend_ioctl().

If you need it only for debugging frontends connected via i2c
you could maybe just use i2c-dev. "cat /sys/class/i2c-dev/i2c-?/name"
will tell you which is the right adapter.
