powerpc/44x/bamboo: Fix PCI range

The bamboo dts has a bug: it uses a non-naturally aligned range
for PCI memory space. This isnt' supported by the code, thus
causing PCI to break on this system.

This is due to the fact that while the chip memory map has 1G
reserved for PCI memory, it's only 512M aligned. The code doesn't
know how to split that into 2 different PMMs and fails, so limit
the region to 512M.

powerpc/4xx: Add support for ISA holes on 4xx PCI/X/E

This adds support for ISA memory holes on the PCI, PCI-X and
PCI-E busses of the 4xx platforms. The patch includes changes
to the Bamboo and Canyonlands device-trees to add such a hole,
others can be updated separately.

The ISA memory hole is an additional outbound window configured
in the bridge to generate PCI cycles in the low memory addresses,
thus allowing to access things such as the hard-decoded VGA
aperture at 0xa0000..0xbffff or other similar things. It's made
accessible to userspace via the new legacy_mem file in sysfs for
which support was added by a previous patch.

[POWERPC] Convert remaining dts-v0 files to v1

At the moment we have a mixture of left-over version 0 and new-format
version 1 files in arch/powerpc/boot/dts. This is potentially
confusing to people new to the dts format attempting to figure it out.

So, this patch converts all the as-yet unconverted dts v0 files and
converts them to v1. They're mechanically-converted, and not hand
tweaked so in some cases they're not 100% in keeping with usual v1
style, but the convertor program does have some heuristics so the
discrepancies aren't too bad.

I have checked that this patch produces no changes to the resulting
dtb binaries.

[POWERPC] Start removing linux,network-index in favour of aliases

This patch alters the bootwrapper for a number of machines (roubhly
all 4xx based cuboot or treeboot platforms) to use aliases instead of
the linux,network-index hack to work out which MAC address to attach
to which ethernet device node.

The now obsolete linux,network-index properties are removed from the
corresponding device trees. This won't break backwards compatiblity,
because in cases where this fixup code is relevant, the device tree is
part of the kernel image.

The references to linux,network-index are removed from
booting-without-of.txt. Not only is it now deprecated, but as a hack
applicable only when the device tree blob and fixup code were in the
same image, this property never belonged in booting-without-of.txt
which describes the interface between the kernel and firmware or
bootloaders which produce a device tree. By the time the device tree
reaches the kernel, all the MAC addresses must be fully filled in.
