ARM: mvebu: add support for Allied Telesis x530
This is a range of stackable network switches. The SoC is Armada-385 and there are a number of variants with differing network port configurations. The DP variants are intended for a harsher operating environment so they use a different i2c mux and fit industrial-temp parts.
