The caller usually has it and it avoids additional mftb() which
can be expensive.

[stewart@linux.vnet.ibm.com: fix run-timer unit test]

Due to the lack of SLW timed interrupt support, we take the opportunity
to check out timers on any incoming interrupt. However we really don't
want to do that for the background pollers.

These have no expiry and get called whenever the opal pollers run,
they are intended to replace most opal pollers and allow the same
code in drivers to chose between a poller or a timer based on things
like interrupt availability for example.
The other advantage over existing pollers (which I hope to deprecate)
is that they are protected against re-entrancy (while still running
without locks held).

For now running off the event pollers, that will improve once we get
delayed interrupts from the SLW
