Do not reserve cpu spin-table for crash kernel
As of now, the kexec reserves the spin-table for all the CPUs
on an SMP machine. The spin-table is pointed to by the
cpu-release-addr property in the device-tree. Reserving the
spin-table in the crash kernel will cause a BUG(), if the table
lies outside the memory reserved for the crashkernel.
Disable reserving the spin-table regions and use maxcpus=1 to
use only the crashing CPU to boot the crash kernel.
