Do we need to check for outstanding events (and call opal_do_notifier)? The
Linux OPAL-IPMI interface signals an event which the interrupt handler
(opal_interrupt) checks for, but if interrupts aren't functional no event will
be signalled and hence the Linux IPMI layer won't get a response.
It's probably only an issue for lab bring up though as I would expect
interrupts to generally be working...
