From: Frederic Barrat <[email protected]>
The spec defines 3 registers, even though only index 0 and 2 are valid
on POWER9. The same model is used on POWER10. Register 1 is defined
there but we currently don't use it in skiboot. So we can keep
reporting an error on write.
Reported by Coverity (CID 1487176).
