This PR is to backport #14138 to 202012.
- Why I did it
In sfplpm API, the number of logical ports is hardcoded as 64. When a system contains more port than this, the SDK APIs would fail with a trace as below
Enabling low-power mode for port Ethernet0... Traceback (most recent call last):

- How I did it
Remove the hardcoded value of 64. Obtained the number of logical ports from SDK
- How to verify it
Manual testing
