Add a driver with initial support for the Arrow SpeedChips XRS7000 series of gigabit Ethernet switch chips which are typically used in critical networking applications. The switches have up to three RGMII ports and one RMII port. Management to the switches can be performed over i2c or mdio. Support for advanced features such as PTP and HSR/PRP (IEC 62439-3 Clause 5 & 4) is not included in this patch and may be added at a later date.
