Full support of ARM-64 (aarch64)

Our SO3 operating system is now fully supporting ARM 64-bit (called aarch64) architecture.
User and kernel space is full functional, except the signal handling in user space which is still under porting (should be available very soon).

Currently, the port is available in a dedicated branch 23-porting-on-aarch6.

It will be merged in the master after our internal review process.

Don’t hesitate to give a try and report us any possible issue.

I’m looking for the support of a framebuffer in the QEMU/virt machine similar to the pl111 available in vexpress (32-bit) machine.
Such a framebuffer would be used with LVGL for example.
