Also add dts file to support HiKey960 development board which based on Hi3660 SoC. The output console is earlycon "earlycon=pl011,0xfdf05000". And the con_init uart5 with a fixed clock, which already configured at bootloader. When clock is available, the uart5 will be modified. Tested on HiKey960 Board.
