The accessor would now only need to set the bool, while it had at least
some logic before.
TBH I don't see the point of having an accessor which is just setting a
variable to "true". But if you like it better, I can keep it.
Another possibility would be to move the arch_thaw_secondary_cpus_begin()
and arch_thaw_secondary_cpus_end() functions to cacheinfo.c, resulting
in only a single place outside of cacheinfo.c setting the variable (in
theory the arch_thaw_secondary_cpus_*() functions could just be redefined
to the accessor and cache_aps_init(), but this would be rather hacky IMO).
