Add initial devicetree support for Hisilicon Hi3670 SoC which is similar to Hi3660 SoC with NPU support. This SoC has Octal core BigLittle CPUs in two clusters(4 * A53 & 4 * A73). Only UART6 has been added for console support which is pre configured by the bootloader. A fixed clock is sourcing the UART6 which will get replaced by the clock driver when available.
