ARM: dts: AM4372: Add PRUSS MDIO controller node
The PRU-ICSS1 instance on AM437x SoCs has a MDIO sub-module that
can be used to control external PHYs associated with the Industrial
Ethernet peripherals within the PRUSS. The MDIO module used within
this PRU-ICSS is an instance of the MDIO Controller used in TI
Davinci SoCs. The same bus frequency of 1 MHz is chosen as the
regular MDIO node. Note that there is no MDIO node added to the
smaller PRU-ICSS0 instance as the MDIO pins are not pinned out.
The node is added to the common am4372 dtsi file and is disabled.
This needs to be enabled in the respective board files using the
relevant AM437x SoCs supporting PRUSS and where the ethernet is
pinned out and connected properly.
