ARM: Implement kexec-hardboot

"Allows hard booting (i.e., with a full hardware reboot) to a kernel
previously loaded in memory by kexec.  This works around the problem of
soft-booted kernel hangs due to improper device shutdown and/or
reinitialization."
More info in /arch/arm/Kconfig.

Original author: Mike Kasick <mike@kasick.org>

Vojtech Bocek <vbocek@gmail.com>:
  I've ported it to hammerhead, it is based of my mako/grouper port, which is
  based of Asus TF201 patch ported by Jens Andersen <jens.andersen@gmail.com>

  Hammerhead is the first device I've ported this patch to which uses
  device tree binary instead of atags. It is also rather picky - its
  bootloader erases first 128MB of RAM on reboot, so following hacks had
  to be applied:
  * Copy dtb to location passed in r2 before jumping to kexecd' kernel,
    the kernel would just freeze when I left dtb above 128MB of RAM.
  * Copy kexecd' kernel to location in the first 128MB before jumping to it,
    the decompressor operates very slowly if the kernel is above the cached
    area, copying it lower and decompressing it afterwards is much faster.

  Same as my mako/flo patches, the guest kernel does not require any
  modifications, kexec-hardboot is equivalent to standard kexec.

  To support dtb, following commit was backported from the mainline:
    commit 4cabd1d9625c7d88acd143f4021fbef75394f154
    Author: Matthew Leach <matthew.leach@arm.com>
    Date:   Fri Sep 21 18:56:02 2012 +0100

      ARM: 7539/1: kexec: scan for dtb magic in segments

      This patch allows a dtb to be passed to a new kernel using the kexec
      mechinism.

      When loading segments from userspace, scan each segment's first four
      bytes for the dtb magic. If this is found set the kexec_boot_atags
      parameter to the relocate_kernel code to the phyical address of this
      segment.
