[ Upstream commit 194eafc9c1d49b53b59de9821fb63d423344cae3 ]
Because a dependency on HAS_IOMEM and OF was added for the ADI AXI ADC driver, this makes the AD9467 driver have some build/dependency issues when OF is disabled (typically on ACPI archs like x86).
This is because the selection of the AD9467 enforces the ADI_AXI_ADC symbol which is blocked by the OF (and potentially HAS_IOMEM) being disabled.
To fix this, we make the AD9467 driver depend on the ADI_AXI_ADC symbol. The AD9467 driver cannot operate on it's own. It requires the ADI AXI ADC driver to stream data (or some similar IIO interface).
So, the fix here is to make the AD9467 symbol depend on the ADI_AXI_ADC symbol. At some point this could become it's own subgroup of high-speed ADCs.
