C/P v2:
I don't think the driver will get to be fully agnostic after this
patch because for instance the ahci_platform_get_resources() method
directly uses the OF-available functions, walks over the OF subnodes,
touches the OF-properties, etc. So AFAICS in order to be fully OF/ACPI
agnostic the entire libahci_platform.o driver needs to be converted
too, but it's not trivial at all.
Anyway as a start this patch looks good.
