Hmm, this becomes a bit complicated.
We got here because we needed to add a depends on HAS_IOMEM for the
ADI_AXI_ADC (due to the s390 arch).
Maybe a better fix would be for AD9467 to depend on ADI_AXI_ADC.
The AD9467 driver can't function without the ADI_AXI_ADC driver.

It is a little early to move this to a "high-speed ADC" subgroup.
