ethernet: Add new driver for Marvell Armada 375 network unit
This commit adds a new network driver for the network controller in Marvell Armada 375 SoC. Given the controller is very different from the ones in the other Marvell SoCs that use the mv643xx_eth (Kirkwood, Orion, Discovery) and mvneta (Armada 370/38x/XP) drivers, a new driver is needed.

+* Marvell Armada 375 Ethernet Controller (PPv2)
+
+Required properties:
+
+- compatible: should be "marvell,armada-375-pp2"
+- reg: addresses and length of the register sets for the device.
+ Must contain the following register sets:
+ - common controller registers
+ - LMS registers
+ In addition, at least one port register set is required.
+- clocks: a pointer to the reference clocks for this device, consequently:
+ - main controller clock
+ - GOP clock
+- clock-names: names of used clocks, must be "pp_clk" and "gop_clk".
+
+The ethernet ports are represented by subnodes. At least one port is
+required.
+
+Required properties (port):
+
+- interrupts: interrupt for the port
+- port-id: should be '0' or '1' for ethernet ports, and '2' for the
+ loopback port
+- phy-mode: See ethernet.txt file in the same directory
+
+Optional properties (port):
+
+- marvell,loopback: port is loopback mode
+- phy: a phandle to a phy node defining the PHY address (as the reg
+ property, a single integer). Note: if this property isn't present,
+ then fixed link is assumed, and the 'fixed-link' property is
+ mandatory.
+
+Example:
+
+ethernet@f0000 {
+ compatible = "marvell,armada-375-pp2";
+ reg = <0xf0000 0xa000>,
+ <0xc0000 0x3060>,
+ <0xc4000 0x100>,
+ <0xc5000 0x100>;
+ clocks = <&gateclk 3>, <&gateclk 19>;
+ clock-names = "pp_clk", "gop_clk";
+ status = "okay";
+
+ eth0: eth0@c4000 {
+ interrupts = <GIC_SPI 37 IRQ_TYPE_LEVEL_HIGH>;
+ port-id = <0>;
+ status = "okay";
+ phy = <&phy0>;
+ phy-mode = "gmii";
+ };
+
+ eth1: eth1@c5000 {
+ interrupts = <GIC_SPI 41 IRQ_TYPE_LEVEL_HIGH>;
+ port-id = <1>;
+ status = "okay";
+ phy = <&phy3>;
+ phy-mode = "gmii";
+ };
+};
