arm: 96boards: Add support for Hikey960

Browse Source 
Add support for Hikey960 board from HiSilicon based on their Kirin960 SoC.

Peripherals supported:

1. GPIO
2. UART
3. I2C

For GPIO only Chardev interface has been added since this board only supports
>=4.15 kernel and using legacy sysfs interface is highly discouraged.
