[PATCH net-next v3 3/4] ARM: dts: aspeed: ast2600-evb: Configure RGMII delay for MAC

[Jacky Chou <jacky_chou@aspeedtech.com>]

This change sets the rx-internal-delay-ps and tx-internal-delay-ps
properties to control the RGMII signal delay.
The phy-mode for MAC0–MAC3 is updated to "rgmii-id" to enable TX/RX
internal delay on the PHY and disable the corresponding delay
on the MAC.
