[PATCH v4 2/2] arm64: dts: ten64: add board controller binding

The board (micro)controller[1] is responsible for functions such as
power supply sequencing, SoC reset as well as serial/MAC address storage,
bootcount and scratch registers.

There is currently no Linux kernel driver for this controller, however,
there is a driver in U-Boot which utilises this binding.
