[SCSI] lpfc 8.3.25: Enhancements to Debug infrastructure

Enhancements to Debug infrastructure

- debugfs additions for new hardware.
- Correct stack overflow in lpfc_debugfs_dumpHBASlim_data()
- Correct warning on uninitialized reg_val in lpfc_idiag_drbacc_write()
- Separated the iDiag command for capturing mailbox commands for generic
  issue mailbox command entry point and for BSG multi-buffer handling.
- Added capturing dumping capabiliy of mailbox command and external buffer
  for the completion of the mailbox command so that the outcome can be
  examined.
- Changed all the iDiag command structure data array indexing introduced so
  far with properly defined macros.
- Added SLI4 device PCI BAR memory mapped register read/browse, write-by-
  value, set-bit, and clear-bit methods for both interface type 0 and
  interface type 2.
- Corrected warnings on mbxstatus being uninitialized in error paths in
  lpfc_bsg.c
