Add spi2 and spi3 device nodes for hi3660, and enable them for hikey960.

On HiKey960:
 - SPI2 is wired out through low speed expansion connector.
 - SPI3 is wired out through high speed expansion connector.

We use gpio_034 as power key on hikey960, and set gpio with pull-up
state, when key press the voltage on the gpio will come to lower, and
power key event will be reported.

Add nodes uart0 to uart4 and uart6 for hi3660 SoC.
Enable uart3 and uart6, disable uart5, in hikey960 board dts.

On HiKey960:
 - UART6 is used as default console, and is wired out through low speed
         expansion connector.
 - UART3 has RTS/CTS hardware handshake, and is wired out through low
         speed expansion connector.
 - UART5 is not used in commercial launched boards. So disable it.
 - UART4 is connected to Bluetooth, WL1837.

Add initial dtsi file to support Hisilicon Hi3660 SoC with
support of Octal core CPUs in two clusters(4 * A53 & 4 * A73).

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.
