Bug reported via SourceForge - lpfc does not load on sparc.  The lpfc
driver must byteswap all FCP IOCBs to recover the data into cpu native
format.

Also correct issue of "iotag not found" messages

Analysis:

Timeout of READ_SPARM64 causes call to lpfc_mbox_timeout_handler which
reads psli->mbox_active to determine the timeout mbox.  Timeout
handler then NULL's psli->mbox_active and calls
lpfc_mbx_cmpl_read_sparam(), which on timeout condition, calls
link_down().  link_down() now calls disc_done() which calls
mbox_timeout_hander() again since WORKER_MBOX_TMO is still set, which
goes back to read psli->mbox_active which is already NULL'ed.

Remove redundant if statement in lpfc_mbox_timeout_handler.  pmbox is
assigned psli->mbox_active so there is no need to check if it actually
equals psli->mbox_active.

Fix issue where all hosts connected to SAN get spammed with nodev
message when other initiators go away.  Display nodev message only
when FC targets go away.  However this behavior will be overridden if
LOG_DISCOVERY is set.

 - rename PGP/HPH to lpfc_pgp/lpfc_hgp
 - use __le32 types for the members to start fixing sparse -Wbitwise
   issues
 - remove lpfc_sli.MBhostaddr, we can always use the pointer from
   SLI2_DESC directly
