Joe Perches 3db8cc1065 [SCSI] bnx2fc: Reduce object size by consolidating formats
Deduplication of formats and consolidating tests
makes the object much smaller.

Add bnx2fc_debug.c, add functions for a few logging
functions (BNX2FC_IO_DBG, BNX2FC_TGT_DBG, BNX2FC_HBA_DBG).
Use printf extension %pV.
Add and use pr_fmt and pr_<level>.
Move the debug #include below structure definitions.
