isci: Convert ATA defines to Linux native defines 

* 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
