[media] tea575x-tuner: mark VIDIOC_S_HW_FREQ_SEEK as an invalid ioctl
The tea575x-tuner framework can support the VIDIOC_S_HW_FREQ_SEEK for only some of the tea575x-based boards. Mark this ioctl as invalid if the board doesn't support it. This fixes an issue with S_HW_FREQ_SEEK in combination with priority handling: since the priority check is done first it could return -EBUSY, even though calling the S_HW_FREQ_SEEK ioctl would return -ENOTTY. It should always return ENOTTY in such a case.
