This introduces a kind of virtual ISM device loopback-ism for SMCDv2.1.
loopback-ism is implemented by software and serves inter-process or
inter-container SMC communication in the same OS instance. It is created
during SMC module loading and destroyed upon unloading. The support for
loopback-ism can be configured via CONFIG_SMC_LO.

Don't forget to update "s/virtual/emulated/" later. ;-)
