Kebo Liu 46e57e050c [Mellanox] Refactor SFP related platform API and plugins with new SDK API (#5326)
Refactor SFP reset, low power get/set API, and plugins with new SDK SX APIs. Previously they were calling SDK SXD APIs which have glibc dependency because of shared memory usage.

Remove implementation "set_power_override", "tx_disable_channel", "tx_disable" which using SXD APIs, once related SDK SX API available, will add them back based on new SDK SX APIs.
