isci: merge remote_device substates into a single state machine
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.
