scsi: mpt3sas: Define hba_port structure

Browse Source 
Define a new hba_port structure which holds the following variables:

 - port_id: Port ID of the narrow/wide port of the HBA

 - sas_address: SAS Address of the remote device that is attached to the
   current HBA port

 - phy_mask: HBA's phy bits to which above SAS addressed device is attached

 - flags: This field is used to refresh port details during HBA reset
