This patch adds support for 405GPr processors with optional
new mode strapping. ibm405gp_fixup_clocks() can now be used
for 405GP and 405GPr CPUs.

This is in preparation of porting the cpci405 platform support
from arch/ppc to arch/powerpc.

This patch also adds ibm405ep_fixup_clocks() to support
405EP CPUs from the boot wrapper.

Currently we have some limitations in the 4xx PCIe driver and can't
support all possible PCIe busses. But the current limits in the
dts file are quite low (only 16 busses per RC). This patch increases
the number to 64 per RC.

Recent DTC versions disallow certain special characters in full paths without
being quoted with {}.  That however breaks compatibility with older DTC
versions.  Work around this by renaming the CPU nodes for the 4xx files to a
generic node name, and specify the processor type in the model property of the
CPU node.

The recent changes from Benjamin Herrenschmidt to the ibm_newemac now
make it possible to support other 4xx variants by just defining the
correct properties in the device tree. In this case of the 405EX we
need to define "has-mdio" in the RGMII node and "has-inverted-stacr-oc"
and "has-new-stacr-staopc" in the EMAC node same as on the 440EPx.

This patch adds runtime detection of the 440SPe revision A chips. These
chips are equipped with a slighly different PCIe core and need special/
different initialization. The compatible node is changed to
"plb-pciex-440spe" ("A" and "B" dropped). This is needed for boards that
can be equipped with both PPC revisions like the AMCC Yucca.

This removes a bogus empty "ranges" property in the EBC device node
of the Bamboo board device-tree.

The "ranges" property should be created by the wrapper code when it is
implemented.  Until then, remove the empty property since it incorrectly
implies that there is a 1:1 address mapping between the EBC and the OPB.

This also fixes a warning from newer DTCs.

This reworks the boot wrapper library function that probes
the chip clocks. Better separate the base function that is
used on 440GX,SPe,EP,... from the uart fixups as those need
different device-tree path on different processors.

Also, rework the function itself based on the arch/ppc code
from Eugene Surovegin which I find more readable, and which
handles one more bypass case. Also handle the subtle difference
between 440EP/EPx and 440SPe/GX, on the former, PerClk is derived
from the PLB clock while on the later, it's derived from the OPB.

Brings EP405 support to arch/powerpc. The IRQ routing for the CPLD
comes from a device-tree property, PCI is working to the point where
I can see the video card, USB device, and south bridge.

This should work with both EP405 and EP405PC.

I've not totally figured out how IRQs are wired on this hardware
though, thus at this stage, expect only USB interrupts working,
pretty much the same as what arch/ppc did.

Also, the flash, nvram, rtc and temp control still have to be wired.
