The GPIO LEDS driver now has a default state of "keep". Update the Warp DTS
and platform file to take advantage of this new state. This removes the
hardcoding of the two LEDs on the Warp.

Now that leds-gpio is a proper OF platform driver, the Warp can use
the leds-gpio driver rather than the old out-of-kernel driver.
One side-effect is the leds-gpio driver always turns the leds off
while the old driver left them alone. So we have to set them back to
the correct settings.

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.

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.
