1) Need to unregister 2 ports per of_device.
2) Need to of_iounmap() 1 mapping per of_device.
3) Need to free up the IRQ only after all devices
have been unregistered.

Happily, life is much simpler on 32-bit sparc systems.
The "intr" property, preferred over the "interrupts"
property is used-as. Some minor translations of this
value happen on sun4d systems.
The stage is now set to rewrite the sparc serial driver
probing to use the of_driver framework, and then to convert
all SBUS, EBUS, and ISA drivers in-kind so that we can nuke
all those special bus frameworks.

Do IRQ determination generically by parsing the PROM properties,
and using IRQ controller drivers for final resolution.
One immediate positive effect is that all of the IRQ frobbing
in the EBUS, ISA, and PCI controller layers has been eliminated.
We just look up the of_device and use the properly computed
value.
The PCI controller irq_build() routines are gone and no longer
used. Unfortunately sbus_build_irq() has to remain as there is
a direct reference to this in the sunzilog driver. That can be
killed off once the sparc32 side of this is written and the
sunzilog driver is transformed into an "of" bus driver.

This needs to be a unique interrupt source because we do
not have a register or similar to poll to make sure the
IRQ is really for us. We do not have any dev_id to pass
in anyways, and the generic IRQ layer is now enforcing
that when SA_SHIRQ is specified, dev_id must be non-NULL.

On sparc64 we don't need to do this because the resource
values are large enough to encode the full physical address.

The idea is to fully construct the device register and
interrupt values into these of_device objects, and convert
all of SBUS, EBUS, ISA drivers to use this new stuff.
Much ideas and code taken from Ben H.'s powerpc work.

Totally unused.
We need to traverse the list of global IRQ translaters,
so storing it in the per-bus structures was useless.

FIXADDR_TOP is used for HIGHMEM and for upper limit of vmalloc area on
32bit kernel. TX39XX and TX49XX have "reserved" segment in CKSEG3
area. 0xff000000-0xff3fffff on TX49XX and 0xff000000-0xfffeffff on
TX39XX are reserved (unmapped, uncached) therefore can not be used as
mapped area.
