[SCSI] bfa: Add support to store driver configuration in flash.
- Added dconf (Driver Config) BFA sub-module. - The dconf sub-module provides interfaces and manages flash writes to the flash DRV parition. - dconf sub-module also ensures that the whole 64K DRV partition is updated on a flash write. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
