Summary
Query the firmware for the LEDs on each physical port and expose
/dev/led/bnxt* only when alternate blinking is supported.  Configure
every LED in the advertised group for identification and restore its
default firmware state before a function reset.

This is a structural port of DPDK bnxt HWRM identification path,
confirmed against Linux where old hwrm (0x10601) was observed.
Test Plan

I would have to go dig through my tubs-o-NICs at my lab to find suitable HW so this has not been witnessed for sensible LED function.

echo 1 > /dev/led/bnxt0
and sight check is reasonable. Could monitor the registers also.
