Add Loopback support for SLI4 adapters
- Add Basic support for SLI4 Loopback.
(CR 124951, 125766, 124951, 125843, 125832, 125843)
- Added missing protection in setting/clearing of phba->link_flag bit
field (CR 125994)
- Use link type and link number obtained from READ_CONFIG mailbox
command. (CR 126264)
