linux/acpi.h includes irqdomain.h which includes of.h. Break the include
chain by replacing the irqdomain include with forward declarations for
struct irq_domain and irq_domain_ops which is sufficient for acpi.h.

This causes build issues in linux-next, so I've dropped the series.  I
will be happy to pick it up again when the build issues are addressed,
though.

Thanks!

Is it just the one in pata_macio.c or are there others you are aware of?
