This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.
Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.
Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

The libfdt.h file is the definition file for libfdt. It is unnecessary
to include other fdt header files (the necessary ones are pulled in
by libfdt.h).

This patch moves some ppc4xx related headers from the common include
directory (include/) to the powerpc specific one
(arch/powerpc/include/asm/). This way to common include directory is not
so cluttered with files.

This patch changes the behaviour of the fdt_fixup_nor_flash_node()
function. Now it doesn't patch the size of the "reg" property with the
chip-select size, but with the size returned from the new function
flash_get_bank_size(). This function will return per weak default the
flash size of the bank (bank = chip-select numer) detected by the flash
driver. If this does not fit your needs, this function may be overridden
by a board specific one.
For this the parameters needed to be changed. So I intentionally squashed
the PPC4xx stuff using this routine into this patch. Otherwise it would
not be git-bisectable anymore.
The board specific function for the AMCC/APM Ebony eval board is now
included in this patch version.

As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.
Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.
