---------------------------

When CPUs come online the original configuration should be restored.
Once the maximum partid is known, allocate an configuration array for
each component, and reprogram each RIS configuration from this.

The MPAM spec describes how multiple controls can interact. To prevent
this happening by accident, always reset controls that don't have a
valid configuration. This allows the same helper to be used for
configuration and reset.
