[Celestica Seastone] fix multi sonic platform issues (#13356)
Why I did it
Fix the following issues for Seastone platform:

- system-health issue: show system-health detail will not complete #9530, Celestica Seastone DX010-C32: show system-health detail fails with 'Chassis' object has no attribute 'initizalize_system_led' #11322
- show platform firmware updates issue: Celestica Seastone DX010-C32: show platform firmware updates #11317
- other platform optimization

How I did it
Modify and optimize the platform implememtation.

How to verify it
Manual run the test commands described in these issues.
