[SCSI] bfa: Add PowerPC support and enable PCIE AER handling.
- Added few missing endian swap changes to support BFA on PowerPC. - Added PCIE AER support to BFA: a) Implemented the PCI error handler entry points. b) Made changes to FCS state machine to handle STOP event from the PCI error detected entry point. c) Made changes to the IO Controller state machine to handle SUSPEND event from the PCI error detected entry point. d) Made changes to restart the BFA operations on a slot_reset completion.
