a8k: pm: extend MSS_TRIGGER_TIMEOUT

Very rarely, during cpuidle operations the following error
is seen: "PM MSG Trigger Timeout".
This is caused by slow handling of message interrutps
in the PM FW running on CM3 (under heavy PM operation load).

This is not a real issue, so we extend the timeout to
avoid the error prints.
