Lan966x has: 2 integrated PHYs, 3 SerDes and 2 RGMII interfaces. Which
requires to be muxed based on the HW representation.

So add constants for each interface to be able to distinguish them.

be connected to a gpio. The current driver implementation will return an
error in these cases. Therefore, make devm_gpiod_get optional.
