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";
};
};
