ARM: dts: aspeed: zaius: Enable NC-SI mux
The Zaius motherboard has muxes for the RMII lines from the BMC to:
- BCM5719 LAN on motherboard (LOM)
- OCP mezzanine connector
- HDMI form factor connector
Assert the active-low enable line for the muxes. Due to the AST2500
default internal pull-down resistors, the muxes selection lines will
be low. This implicitly selects the LOM for NC-SI.
The NC-SI interface will show up as network interface eth0.
