powerpc/pseries: Add a helper for form1 cpu distance
[ Upstream commit ef31cb83d19c4c589d650747cd5a7e502be9f665 ]
This helper is only used with the dispatch trace log collection.
A later patch will add Form2 affinity support and this change helps
in keeping that simpler. Also add a comment explaining we don't expect
the code to be called with FORM0
