Currently fdt for crash kernel is not updated on cpu hotplug remove,
which can lead to the following XIVE warnings on the crash kernel
bringup.
[ 0.630795][ T1] xive: H_INT_GET_QUEUE_INFO cpu=16 prio=6 failed -55
[ 0.630912][ T1] xive: Error -55 getting queue info CPU 16 prio 6
[ 0.680899][ T1] xive: H_INT_GET_QUEUE_INFO cpu=17 prio=6 failed -55
[ 0.681000][ T1] xive: Error -55 getting queue info CPU 17 prio 6
Fixing this by updating crash fdt on cpu hotplug remove path also.
