Log:
  powerpc: preload_addr_relocate is no longer necessary for booke
  
  The same behavior was moved to machdep.c, paired with AIM's relocation,
  making this redundant.  With this, it's now possible to boot FreeBSD with
  ubldr on a uboot Book-E platform, even with a
  KERNBASE != VM_MIN_KERNEL_ADDRESS.
