Update phy-credo package to fix sonic-mgmt test issue and support the AOC module.

[abohanyang]

Why I did it

1. Fix an error on platforms with external phy but not using phy-credo service. Some sonic-mgmt tests fail due to this error.
2. Add AOC support for platforms that use the phy-credo service.

How I did it

1. Gracefully return if the platform does not use the phy-credo service.
2. Determine the medium type based on the compliance code.

How to verify it

1. Sonic-mgmt tests no longer fail due to this phy-credo error.
2. A port with an AOC module can come up reliably.

@abohanyang is this change a cherry-pick of a master change? Why is it directly targeting 202205 branch?

Hi @yxieca

@abohanyang is this change a cherry-pick of a master change? Why is it directly targeting 202205 branch?

No. This change is not in the master branch yet. I have a separate PR for the master branch (#16280). I am not sure if I should wait for the cherry-picking or create a PR targeting 202205 directly.

@prgeor, @StormLiangMS please assess if this change should be cherry-picked to 202205. Thanks.

@abohanyang which platform is this fix tested? Is AOC managed by Xcvrd?

Hi @prgeor ,

This change addresses two issues:
Issue 1 "Fix an error on platforms with external phy but not using phy-credo service. Some sonic-mgmt tests fail due to this error"

• We tested this fix against 7800R3-48CQ2-LC and 7800R3-48CQM2-LC and confirmed that phy-credo service exits gracefully on 7800R3-48CQM2-LC.

Issue 2 "Add AOC support for platforms that use the phy-credo service."

• The phy-credo service updates the firmware settings of Credo Serdes based on the transceiver type. The AOC module is still managed by the Xcvrd.
• 7800R3-48CQ2-LC uses phy-credo service. 7800R3-48CQM2-LC does not use phy-credo service. So we tested AOC modules on 7800R3-48CQ2-LC.
