Per previous discussions on this patch, CPU_COMPLEX_* will be renamed
CPU_CLUSTER_*, and will refer to all the gunk around the CPU that may
be shared by another CPU.  In this series, it is only used to save and
restore the GIC distributor registers, but it could be used for L2 as
well, if any platforms can agree on what needs to happen to the L2,
and when.
