[Skiboot] [PATCH v2 06/52] test-ipmi-hiomap: Add ability to delay some IPMI messages

[Andrew Jeffery]

The initial implementation delivered all BMC-initiated SELs immediately
after the delivery of the last response to the host. In some
circumstances we want slightly more control over how this works, so
introduce a means to manually advance the scenario in the test case.
