[SCSI] mvsas: add support for 94xx; layout change; bug fixes 

This version contains following main changes
  - Switch to new layout to support more types of ASIC.
  - SSP TMF supported and related Error Handing enhanced.
  - Support flash feature with delay 2*HZ when PHY changed.
  - Support Marvell 94xx series ASIC for 6G SAS/SATA, which has 2
88SE64xx chips but any different register description.
  - Support SPI flash for HBA-related configuration info.
  - Other patch enhanced from kernel side such as increasing PHY type
