x86: ioapic: Add OF bindings for IO_APIC
ioapic_xlate provides a translation from the information in device tree
to ioapic related informations. This includes
- obtaining hw irq which is the vector number "=> pin number + gsi"
- obtaining type (level/edge/..)
- programming this information into ioapic
ioapic_add_ofnode adds an irq_domain based on informations from the device
tree. This information (irq_domain) is required in order to map a device to
its proper interrupt controller.
[ tglx: Adapted to the io_apic changes, which let us move that whole code
to devicetree.c ]
