A substate is just a state, so uplevel the smp and stp device substates.
Three tricks at work here:
1/ scic_sds_remote_device_ready_state_enter: needs to know the the device type
so it can immediately transition to a stp or smp ready substate.
2/ scic_sds_remote_device_ready_state_exit: needs to know the device type. In
the ssp case the device is no longer ready, in the stp, and smp case we have
simply exited to a ready "substate".
3/ scic_sds_remote_device_resume_complete_handler: The one location
where we directly check the current state against
SCI_BASE_REMOTE_DEVICE_STATE_READY needed to comprehend the possible ready
substates.

An lldd need never look at the contents of an smp_discover_response frame.
Kill the remaining locations where isci is looking at it:
1/ covering for expanders that do not set the stp_attached bit (already
handled by sas_ex_discover_end_dev)
2/ an overkill method to notifiy the rest of the driver about remote_device
sas addresses

This is step 1 of removing the contortions to:
1/ unparse expander phy data into a smp discover frame
2/ open-code-parse the smp discover fram into a domain_device.dev_type equivalent
libsas has already spent cycles determining the dev_type, so now that
scic_sds_remote_device is unified with isci_remote_device we can
directly reference dev_type.
This might also change multi-level expander detection as we previously only
looked at dev_type == EDGE_DEV and we did not consider the FANOUT_DEV case.
