Use Linux native swab32() call instead of SCIC_SWAP_DWORD().

We need to swab() because the hardware munges the data into a
"big-endian dword" stream which is byte-swapped from the sas definition
regardless of host endian.

Moved the actual data structure that's read from the phy register to phy
header.  Removed the parsing of identify address frame protocol bits as
that seemed not necessary and we can use existing information.

Converting to Linux native format. However the isci driver does a lot of
the calculation based on the max size of this data structure and the
Linux data structure only has a pointer to the response data. Thus the
sizeof(struct ssp_response_iu) will be incorrect and we need to define
the max size.

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.
