[Mellanox] Update FW upgrade script to use 'mlxfwmanager -d' option for specifying MST device in FW burn operation (#6541)

Browse Source 
**- Why I did it**
Reduce the time it takes for the ASIC FW burn as part of the automatic FW upgrade procedure.

**- How I did it**
Add -d option to mlxfwmanager tool to use the faster MST device and not the default one which is not the fastest one.

**- How to verify it**
I manually changed ASIC FW followed by reboot command in order for FW upgrade to take place on deinit.
I manually changed ASIC FW followed by hard reset in order for FW upgrade to take place on init.
