[PATCH resend v4 2/3] dt-bindings: phy: Add constants for lan966x serdes

[Horatiu Vultur <horatiu.vultur@microchip.com>]

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.
