#1335152 — [PATCH 4/4] x86/msr: Document msr-index.h rule for addition

From: Borislav Petkov <bp@suse.de>

In order to keep this file's size sensible and not cause too much
unnecessary churn, make the rule explicit - similar to pci_ids.h - that
only MSRs which are used in multiple compilation units, should get added
to it.
