external/mambo: Add POWER10 small-core mode

If the SMT configuration is not 8, set small-core mode in SIM_CTRL1
and PVR registers.

Also allow only 1, 2, 4, or 8 threads, and only allow 1 and 2 threads
if there is only one processor configured. This helps avoid strange
crashes due to thread/core enumeration problems with unexpected threads
per core.
