Add Support for riscv64


At the beginning, I arrived from almalinux and did a lot of work to switch to you.
And also I had requested the fact of supporting LXC which for me was imperative.
Today I have another important request.
It supports the riscv64 architecture with also a version for LXC.
I hope this is the right place for this request.
If necessary I can go through github or something else.

Also i recommend to work on this Hardwares:
1 is Starfive VisionFive 2 : 开发板

For Kernel mainline support you can look here : JH7110 Upstream Status | RVspace

Best Regards
