fatal() nearly does the same thing as die() does, so this is kind of
duplicate. Remove fatal() and use die() instead.

As of now, the kexec reserves the spin-table for all the CPUs
on an SMP machine. The spin-table is pointed to by the
cpu-release-addr property in the device-tree. Reserving the
spin-table in the crash kernel will cause a BUG(), if the table
lies outside the memory reserved for the crashkernel.
Disable reserving the spin-table regions and use maxcpus=1 to
use only the crashing CPU to boot the crash kernel.

V2: Fix a compile error
Like commit 28d4ab53280853d2aeefdfb7c369331e89ab9ac2
("Add generic debug option"), this one moves code
under #if DEBUG to --debug on ppc arch.
Sorry that I still can't find a ppc32 machine to test this.

It was possible to not add enough space when we allocate
more space for more memory reserve regions, this was because
we were incorrectly accounting for the size of a reserve
region. This corrects the assumed size for a resize region

We always remove the old entry, and add it back if it is needed
on for the kexec'ed kernel

Currently, we can add a lot of reservations over a small range, this
does a simple check to verify the previous entry is not the same
as the current one and skips it if so

Currently, the device tree is passed as is. You can optionally
update the command line and specifically listed nodes but nothing
is updated automatically.
This patch updates the memreserve regions, memory node, initrd
nodes and attempts to make the device tree look as it should. Some
code is borrowed from the u-boot routines which do similiar things
Also, now if no flat device tree is passed to kexec it will attempt
to rebuild one from the /proc/device-tree file system to use for
the kexec'ed kernel for both uImage and elf formats

A few device nodes are dynamically determined by the bootloader (MAC address,
memory size, ..) and are not part of the device tree. The kernel command line
is also read from dtb and usually not part of the device tree.
With the libfdt it is now easy to add/replace nodes in the device tree.
The user may specify "--reuse-node=/memory/reg" to update the memory/reg
node to what ever is now. This requires the kernel to export the device
tree via the procfs in /proc/device-tree.
