ARM: dts: lan966x: add MIIM nodes
Add the MDIO controller nodes. The integrated PHYs are connected to the second controller. This controller also takes care of the resets of the integrated PHYs, thus it has two memory regions. The first controller is routed to the external MDIO/MDC pins. By default, they are disabled.
