cpu/hotplug: Increase the number of dynamic states

The dynamically allocatable hotplug state space can be exhausted by
the existing drivers and infrastructure which install CPU hotplug
states dynamically. That prevents new drivers and infrastructure from
installing dynamically allocated states.

Increase the size of the CPUHP_AP_ONLINE_DYN state by 10 to make
room.
