arm64: Add cavium_erratum_23154_cpus missing sentinel

Browse Source 
Qian Cai reported that playing with CPU hotplug resulted in a
out-of-bound access due to cavium_erratum_23154_cpus missing
a sentinel indicating the end of the array.

Add it in order to restore peace and harmony in the world
of broken HW.
