[Mellanox]Correct reboot cause when reboot via power cycle #3597

Ignore reset_sw_reset which indicates rebooted by software.

- What I did
Correct reboot cause when reboot via power cycle by ignoring reset_sw_reset.

process-reboot-cause has the following logic:

  1. check whether there is a hardware reboot cause, if so treats it as the final reboot-cause
  2. otherwise it checks the previously saved reboot cause files in /host/reboot-cause/

Currently we implement "reboot" command via using power cycle. After a power-cycle reboot the reset_sw_reset contains a "1". Originally chassis reboot-cause handling treats it as a hardware-caused reboot and returns it to process-reboot-cause. In this case, the process-reboot-cause treats it as the reboot cause which is wrong.

To resolve that, just don't return hardware reboot cause on reset_sw_reset.

- How I did it
Don't return hardware reboot cause on reset_sw_reset.

- How to verify it
reboot DUT and then check the reboot cause

Also check reboot cause file "reset_sw_reset" which indicates the system was rebooted due to software requesting.

@stephenxs: Should this PR also be cherry-picked into the 201811 branch?
