Subject: ARM: dts: sun7i: lamobo-r1: Fix CPU port RGMII settings

From: Florian Fainelli <[email protected]>

commit 0cdefd5b5485ee6eb3512a75739d09a4090176ed upstream.

The CPU port of the BCM53125 is configured with RGMII (no delays) but this should actually be RGMII with transmit delay (rgmii-txid) because STMMAC takes care of inserting the transmitter delay. This fixes occasional packet loss encountered.
