acpi, hmat: refactor hmat_register_target_initiators()

[ Upstream commit d0376aac59a166cd7bd9d1a9768e31e71002631b ]

Previously, in hmat_register_target_initiators(), the performance
attributes are calculated and the corresponding sysfs links and files are
created too.  Which is called during memory onlining.

But now, to calculate the abstract distance of a memory target before
memory onlining, we need to calculate the performance attributes for a
memory target without creating sysfs links and files.

To do that, hmat_register_target_initiators() is refactored to make it
possible to calculate performance attributes separately.
