Allow keeping track of whether all CPUs have been enabled yet. This allows
us to know whether other CPUs need to be considered when updating
CPU-specific settings such as MTRRs on x86.

The name is a little bit vague. It's unclear whether this indicates
SMP init start or done.

Maybe GD_FLG_SMP_READY ?
