[yang] Commenting out sonic-portchannel import to fix backlink issue

[ghooo]

Why I did it

Commenting out the import to sonic-portchannel because it is breaking the backlink of PORT

Example

{
    "PORT": {
        "Ethernet112": {}
    }
    "PORTCHANNEL": {
        "PortChannel101": {
            "members": [
                "Ethernet112"
            ]
        }
   }
}

The path /PORT/Ethernet112 should have a backlink to /PORTCHANNEL/PortChannel101/members/0 but it is not retrieved correctly.
