Introduce a helper API ofnode_phy_is_fixed_link() to detect whether the ethernet controller connects to a fixed-link pseudo-PHY device.
Note there are two ways to describe a fixed PHY attached to an Ethernet device:
- the new DT binding, where 'fixed-link' is a sub-node of the Ethernet device
- the old DT binding, where 'fixed-link' is a property with 5 cells encoding various information about the fixed PHY
