Ugh, there is a mess around them. Some other ADCs have specific
compatibles, some not, so there is no consistency.

I propose to have device specific compatible with qcom,spmi-iadc
fallback, so basically document the DTS in bindings. Maybe other IADC
will need some quirks, so specific compatible helps here.
