Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

The support for Briq machines has been floating around as patches for
ages. This cleans it up and adds it once for all.
Some of this is based on initial code provided by Karsten Jeppesen
<karsten@jeppesens.com> and mostly rewritten from scratch by me.

This adds the new irq remapper core and removes the old one. Because
there are some fundamental conflicts with the old code, like the value
of NO_IRQ which I'm now setting to 0 (as per discussions with Linus),
etc..., this commit also changes the relevant platform and driver code
over to use the new remapper (so as not to cause difficulties later
in bisecting).
This patch removes the old pre-parsing of the open firmware interrupt
tree along with all the bogus assumptions it made to try to renumber
interrupts according to the platform. This is all to be handled by the
new code now.
For the pSeries XICS interrupt controller, a single remapper host is
created for the whole machine regardless of how many interrupt
presentation and source controllers are found, and it's set to match
any device node that isn't a 8259. That works fine on pSeries and
avoids having to deal with some of the complexities of split source
controllers vs. presentation controllers in the pSeries device trees.
The powerpc i8259 PIC driver now always requests the legacy interrupt
range. It also has the feature of being able to match any device node
(including NULL) if passed no device node as an input. That will help
porting over platforms with broken device-trees like Pegasos who don't
have a proper interrupt tree.

This is needed if we wish to change the size of the resource structures.
Based on an original patch from Vivek Goyal <vgoyal@in.ibm.com> and
Andrew Morton.

The patch removing _machine and converting platforms over to use
define_machine wasn't complete as far as CHRP was concerned. This
adds the define_machine call for CHRP and gets it booting again.

This makes CHRP build again, although it's untested because my Pegasos
is currently in pieces.

SMP still needs more work but UP gets as far as starting userspace
at least. This uses the 64-bit-style code for spinning up the cpus.
