powerpc/kexec: Check crash_base for relocatable kernel
Enforce that the crash kernel region never overlaps the current kernel,
as it will be written directly on kexec load.
Also, default to the previous KDUMP_KERNELBASE if the start is 0.
Other architectures (x86, ia64) state that specifying the start address
0 (or omitting it) will result in the kernel allocating it. Before the
relocatable patch in 2.6.28, powerpc would adjust any other start value
to the hardcoded KDUMP_KERNELBASE of 32M.
