Apparently there are no in-tree users of the platform data struct, so users need to adopt. New users can associate the GPIO lines with the platform device "pcm3008-codec".

This is just wrong, if the device tree assigns the IRQ from a GPIO number this is just incorrect: it is clearly stated that GPIO providers and IRQ providers are orthogonal. It is possible to look up an IRQ to a corresponding GPIO line but this is taking an IRQ and pretending it's a GPIO, which is just semantically wrong. Drop the offending code and treat the IRQ that we get from the device tree as any other IRQ, see for example other codec drivers. The DT bindings for this codec does not have any in-tree DTS files, which may explain why things are weird. As a bonus, this moves the driver away from the legacy include.
