* Removing all intel_sata and intel_ata defines
* Removing the usage of SAT_PROTOCOL_*. We can get everything from sas_task
* Moved SATA FIS types to local sas.h. These defines will have to go
  into include/scsi/sas.h eventually.
* Added offsets for SATA FIS header in order to grab the values

A function call to dereference a pointer is a tad much.

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.

2/ an overkill method to notifiy the rest of the driver about remote_device
   sas addresses
