[PATCH v4 5/6] arm64: dts: rockchip: add the gmac needed node for rk3399

[Caesar Wang]

From: Roger Chen <roger.chen@xxxxxxxxxxxxxx>

The RK3399 GMAC Ethernet Controller provides a complete Ethernet interface
from processor to a Reduced Media Independent Interface (RMII) and Reduced
Gigabit Media Independent Interface (RGMII) compliant Ethernet PHY.

This patch adds the related needed device information.
e.g.: interrupts, grf, clocks, pinctrl and so on.

The full details are in [0].
