Re: [PATCH v4 1/2] net: ti: am65-cpsw-nuss: Enforce pinctrl state on the MDIO child node

The binding represents the MDIO controller as a child device tree node of the MAC device tree node.

The U-Boot driver mostly ignores that child device tree node and just hardcodes the resources it uses to support both the MAC and MDIO in a single driver.

However, some resources like pinctrl muxing states are thus ignored. This has been a problem with some device trees that will put some pinctrl states on the MDIO device tree node, like the SK-AM62 Device Tree does.

Let's rework the driver a bit to create a dummy MDIO driver that we will then get during our initialization to force the core to select the right muxing.
