[PATCH 1/2] arm64: dts: armada-3720-espressobin: Configure RGMII and SMI pins

[Remi Pommarel]

In order to be able to communicate with the 88e6341 switch some pins
have to be repurposed as RGMII and SMI pins.

This fixes ethernet support on system booted via a bootloader that
has not already configured those pins (e.g. mainline u-boot, or vendor
u-boot compiled without ethernet support).
