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.

This driver is for Broadcom Netxtreme II 57712 chip. The following
patch contains the driver sources for bnx2fc driver.  libfc/libfcoe
changes to enable bnx2fc have already gone through the fcoe
tree. bnx2fc is a SCSI low level driver that interfaces with SCSI
midlayer, libfc, libfcoe, cnic modules.  bnx2fc driver uses services
of libfc for slow path operations such as FIP and fabric
discovery. The fast path IO perations are performed after offloading
the session information to the underlying FCoE firmware.
