wifi: brcmfmac: fix gnu_printf warnings



With GCC 13.1 and W=1 brcmfmac has warnings like this:

./include/trace/perf.h:26:16: warning: function 'perf_trace_brcmf_dbg' might be a candidate for 'gnu_printf' format attribute [-Wsuggest-attribute=format]

Add a workaround which disables -Wsuggest-attribute=format in tracepoint.h. I
see similar workarounds in other drivers as well.

Compile tested only.
