[SCSI] aacraid: Add new code for PMC-Sierra's SRC based controller family
Added new hardware device 0x28b interface for PMC-Sierra's SRC based
controller family.
- new src.c file for 0x28b specific functions
- new XPORT header required
- sync. command interface: doorbell bits shifted (SRC_ODR_SHIFT, SRC_IDR_SHIFT)
- async. Interface: different inbound queue handling, no outbound I2O
queue available, using doorbell ("PmDoorBellResponseSent") and
response buffer on the host ("host_rrq") for status
- changed AIF (adapter initiated FIBs) interface: "DoorBellAifPending"
bit to inform about pending AIF, "AifRequest" command to read AIF,
"NoMoreAifDataAvailable" to mark the end of the AIFs
