substate machine is defined. This routine requires no conversion
because we have transitioned out of 'started' and the substate routine
will be called naturally as a result.
There are also no side effects of this conversion on exiting the
'started', state because it only stops the substate machine, which is no
longer relevant for this transaction type.

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.
