Support for the AX3000 SoC, from Harshit Shah <hshah@axiado.com>:

The AX3000 is a multi-core system-on-chip featuring four ARM Cortex-A53
cores, secure vault, hardware firewall, and AI acceleration engines. This
initial support enables basic bring-up of the SoC and evaluation platform
with CPU, timer, UART, and I3C functionality.

The series begins by adding the "axiado" vendor prefix and compatible
strings for the SoC and board. It then introduces the device tree files
and minimal ARCH_AXIADO platform support in arm64.
