The iRMC hardware type has been deprecated since 2019 due to the
third-party CI being offline and the vendor being unresponsive.
Remove the hardware type and all associated interfaces (power,
management, boot, inspect, raid, bios, vendor), configuration,
tests, and documentation.
Additionally, prior to this change, test_manager was implicitly
relying on the irmc driver being imported to make redfish.management
available -- this means these tests were invalidly failing. Those
tests were fixed by importing redfish.management directly and using
it directly (instead of relying on a side-effect).
