Subject: [net-next 3/4] dt-bindings: net: ftgmac100: add rgmii delay properties

Add tx-internal-delay-ps and rx-internal-delay-ps to
configure the RGMII delay for MAC. According to
ethernet-controller.yaml, they use for RGMII TX and RX delay.

In Aspeed desgin, the RGMII delay is a number of ps as unit to
set delay, do not use one ps as unit. The values are different
from each MAC. So, here describes the property values
as index to configure corresponding scu register.
