Fix NIC name changes for ice

[gerald.yang]

[Impact]

This upstream commit introduced that Intel ice driver exports "phys_port_name" in sysfs interface:
37165e3f5664 ice: introduce VF port representor

And “phys_port_name” is used by systemd when renaming NIC,
so when upgrading kernel from 5.15 to 6.8, this causes NIC name changes from ens2f0:
kernel: ice 0000:2a:00.0 ens2f0: renamed from eth0
to ens2f0np0:
kernel: [ 21.217165] ice 0000:2a:00.0 ens2f0np0: renamed from eth0

In some circumstances, bond won't work after upgrading kernel because of its underlying NIC name changed

[Fix]

Later, upstream removed exporting "phys_port_name" in sysfs interface in this commit:
41355365d252 ice: Remove ndo_get_phys_port_name

It's removed in 6.10:
git tag --contains 41355365d252
v6.10

Because phys_port_name is never used, mentioned in the commit message:
ndo_get_phys_port_name is never actually used, as in switchdev
devlink is always being created.

We should make it consistent to not having "npX" in the tail of NIC name

[ Test ]

Install 5.15 and 6.8 kernels on a machine with Intel ice NIC and see if NIC name is the same.

[ Where the problems could occur ]

Since the "phys_port_name" is never actually used, it's find to remove it.

This bug is awaiting verification that the linux/6.8.0-58.60 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux' to 'verification-done-noble-linux'. If the problem still exists, change the tag 'verification-needed-noble-linux' to 'verification-failed-noble-linux'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

This SRU just removes the unused code but turn out it doesn't affect the NIC renaming.
NIC name is usually set by netplan or cloud init, we can safely pick this patch.
