I took these values verbatim from the vendor kernel when adding the core
rk3368 support.
I guess I was overly enthusiastic, that psci worked out of the box for smp,
that I didn't check the latency/residency values enough at that time. As time-
values they are really overly long :-) .
Nevertheless I have inquired now, what the background of those values is.
