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.

Signed-off-by: Dan Williams <dan.j.williams@intel.com>
Instead of filling up tables with default handlers call the default
handler in the only caller.
IMHO the whole state handlers concept is not very suitable for the
isci request. For example there is a single real instance of the
start handler, and we'd be much better off just having a check for
the right state in the only caller, than all this mess. It's
quite similar for the abort handler as well.
Even the actual state machine has a lot of states that are rather
pointless. The initial and constructed states are not needed at all
as the request is not reachable for calls before it's fully set up and
started. And the abort state should be replaced with an abort actions
and a state transition to the completed state.
