A1 is an application processor designed for smart audio and IoT applications,
with Dual core ARM Cortex-A35 CPU. Unlike the previous GXL and G12 series,
there is no Cortex-M3 AO CPU in it.

This serial add basic support for the Amlogic A1 based Amlogic AD401 board:
which describe components as follows: Reserve Memory, CPU, GIC, IRQ,
Timer, UART. It's capable of booting up into the serial console.

The pclk for uart_AO_B need to be fixed once A1 clock driver is merged.
In this version, it rely on bootloader to enable the pclk gate
