net/mlx5e: Add missing ethtool driver info for representors

For all representors added firmware version info to show in
ethtool driver info.
For uplink representor, because only it is tied to the pci device
sysfs, added pci bus info.

Fixes: ff9b85d ("net/mlx5e: Add some ethtool port control entries to the uplink rep netdev")
