arm64: dts: add support for A5 based Amlogic AV400 



Amlogic A5 is an application processor designed for smart audio
and IoT applications.

Add basic support for the A5 based Amlogic AV400 board, which describes
the following components: CPU, GIC, IRQ, Timer and UART.
These are capable of booting up into the serial console.
