Subject: [PATCH 07/10] arm64: dts: ti: k3-am64: MDIO pinmux should belong to the MDIO node

Although usually integrated as a child of an Ethernet controller, MDIO
IP has an independent pinout. This pinout should be controlled by
the MDIO node (so if it was to be disabled for instance, the pinmux
state would reflect that).

Move the MDIO pins pinmux to the MIDO nodes.
