ARM: dts: aspeed: msx4: enable BMC networking via MAC0
Add &mac0, &mdio3, and the ethphy3 PHY node to enable BMC networking
on the AST2600-based NVIDIA MSX4 board. The PHY is attached to MDIO3
at address 2 and uses RGMII with PHY-internal delays.
These nodes were intentionally omitted in commit f28674fab34f ("ARM:
dts: aspeed: Add NVIDIA MSX4 HPM") at Andrew Lunn's request, pending
clarification of the RGMII delay handling. Following his guidance on
linux-aspeed, the bootloader has been modified to stop enabling MAC
clock delays on the SoC side, so phy-mode = "rgmii-id" correctly
results in the PHY adding the required ~2ns delay without any
double-delay from the MAC controller.
The corresponding U-Boot change has been submitted to openbmc/u-boot.
