Subject: bnxt_en: consolidate fw devlink health reporters
Patch-mainline: v5.16-rc1
Git-commit: 2bb21b8db5c0e515549d7d1d0de5dc905a32a338
References: jsc#SLE-18978

Merge 'fw' and 'fw_fatal' health reporters.  There is no longer a need
to distinguish between firmware reporters. Only bonafide errors are
reported now and no reports were being generated for the 'fw' reporter.
