[cel seastone 2] Add 10G SFP1 front port (#8267)

Why I did it
The SFP1 port was disabled in the default configuration.

How I did it
This commit enables the 10G front port for usage.
This was done using a DX030 together with an Arista switch using bcmsh and phy diag xe0 dsc to figure out what lane mappings make sense.

Validated on Celestica Seastone2 DX030.

How to verify it
Own a Celestica DX030
Connect the front SFP1 port to something.
It works :-)
You can do tcpdump -i Ethernet128 -n and you will see both incoming and outgoing LLDP.
