Disable backup regions for BookE in case of a CRASH Dump, as they can

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
CRASH MEMORY RANGES
0000000000000000-0000000006400000
000000000e400000-0000000010000000
Command line after adding elfcorehdr: elfcorehdr=112380K
Command line after adding elfcorehdr: elfcorehdr=112380K savemaxmem=256M
So there were two crash regions when we only needed the one specified
on the command line?
Yes, and isn't that is expected ? The first kernel uses the memory region
(0-100M), (228M,256M). Where the 100-228M is reserved for crash kernel.
Thanks
