[RFC 5/7] cpu: mark ro_mostly_after_init for cpuhp_ap/bp_states

[Hoeun Ryu <hoeun.ryu@gmail.com>]

It would be good that `__ro_mostly_after_init` is marked to cpuhp state
objects. They can not be simply marked as `__ro_after_init` because they
should be writable during module_init/exit. Now that they can be read-only
except during module_init/exit
