arm64: dts: Add devicetree for Hisilicon Hi3670 SoC
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 already configured by the bootloader. A fixed clock is sourcing the UART6 which will get replaced by the clock driver when available.
