Steps to reproduce the issue:

1. Powercycle device and check reboot-cause using 'show reboot-cause' or
2. Run platform_tests/test_reboot.py::test_power_off_reboot

Describe the results you received:

Reboot-cause shows as "Unknown" after power-cycle

Describe the results you expected:

Reboot-cause should be "Power Loss"

@tjchadaga, @sujinmkang Can you please paste the output of "cat /var/log/firmware_versions"?.
If the platform components firmware are not updated, requesting you to upgrade it and rerun the tests.

@aravindmani-1 - Thanks, after firmware upgrade, the status is now " Hardware - Other (Power on reset)" instead of Unknown.
This is the version:
cat /var/log/firmware_versions
BIOS: 2.0.4
FPGA: 0.6
BMC: 1.3
Baseboard CPLD: 9
Switch CPLD 1: 1
Switch CPLD 2: 1

The test case still fails since its looking for "power loss". I guess the script can be updated to handle this.
