powerpc/kdump: Override crash_free_reserved_phys_range to avoid freeing RTAS
The crashkernel region will almost always overlap RTAS. If we free the
crashkernel region via "echo 0 > /sys/kernel/kexec_crash_size" then we will
free RTAS and the machine will crash in confusing and exciting ways.
Override crash_free_reserved_phys_range and check for overlap with RTAS.
