When running on newer OPAL firmware that supports sending extra OPAL_MSG types, we would print a warning on *every* message received. This could be a problem for kernels that don't support OPAL_MSG_OCC on machines that are running real close to thermal limits and the OCC is throttling the chip. For a kernel that is paying attention to the message queue, we could get these notifications quite often. Conceivably, future message types could also come fairly often, and printing that we didn't understand them 10,000 times provides no further information than printing them once.

Applied to powerpc fixes, thanks. https://git.kernel.org/powerpc/c/98da62b716a3b24ab8e77453 cheers
