[DellEmc] Fix port lanes on alternative S5232 SKUs

[bluecmd]

Backport the fix (444cede) that was made for the default SKU
to the alternative SKUs.

Why I did it

The tenGigE1/33 and tenGigE1/34 works with the default SKU configuration, but not with the one I want to use - DellEMC-S5232f-P-25G.

How I did it

I looked at the differences between these SKUs as well as the state in bcmsh and saw that the ps output looked off when Ethernet129 was enabled.

How to verify it

• Connect a device to one of the two 10G slots (not both)
• Load e.g. the 25G SKU: sonic-cfggen -H -k DellEMC-S5232f-P-25G --print-data > /etc/sonic/config_db.json; reboot
• Enable the port: sudo config int startup Ethernet129
• Observe the port still being down: show int status | grep tenGig
• Enable the other port: sudo config int startup Ethernet128
• Observe the first port now being up, while the SFP module being on the wrong slot: show int status | grep tenGig.

E.g.:

admin@localhost:~$ show int status | grep tenGig
Ethernet128              128      10G   9100    N/A           tenGigE1/33  routed      up       up              N/A         N/A
Ethernet129              129      10G   9100    N/A           tenGigE1/34  routed    down       up   SFP/SFP+/SFP28         N/A

Which release branch to backport (provide reason below if selected)

These are the releases the referenced bug fix was included in, but the alternative SKUs were not fixed.
