I expect this driver to grow in functionality over time. Right now, it
does the global init for the DMA. After that all channels execute on
their own without depending on each other. Global init has to be done
first before attempting to do any channel initialization.

There is also implied startup ordering requirements. I was doing this by
using channel driver with the late binding to guarantee that.

As soon as I use module_platform_driver, the ordering gets reversed for
some reason.

If you want to force two probe functions to be called in order, then that's what -EPROBE_DEFER is for.
