DellEMC S6100: Update reboot-cause determination to support new firmware (#5807)

Browse Source 
- Why I did it
For determining reboot-cause while running newer BIOS, SMF firmware.

- How I did it
Made changes in reboot-cause determination script to add support for behavior of newer firmware.

- How to verify it
Performed different type of resets and verified "show reboot-cause" provides the correct reason.
