Knowing the number of active CPUs is not enough to know which ones are
active. This patch adds 2 new functions:
* smp_cpu_addr_from_idx to get the CPU address from the index
* smp_cpu_from_idx allows to retrieve the struct cpu from the index
This makes it possible for tests to avoid hardcoding the CPU addresses.
It is useful in cases where the address and the index might not match.
