kexec: powerpc: crash_dump: No backup region for PPC BookE
Disable backup regions for BookE in case of a CRASH Dump, as they can
be run from anywhere.
The patch introduces --with-booke option to support the BookE.
With the patch, we get :
## On a 256M machine:
# busybox cat /proc/cmdline
init=/bin/init console=ttyS0,16550 crashkernel=128M@100M
# kexec -p root/vmlinux
usable memory rgns size:1 base:6400000 size:8000000
