RISC-V Hardware Platform Validation

[antoinecarme]

New Hardware Architecture : RISC-V

This is a very experimental platform. PyAF intends to work on a not-yet-fully-manufactured hardware (#176 ).

The Sifive dev board (VisionFive 2) is planned through a kickstart project :

https://www.kickstarter.com/projects/starfive/visionfive-2/

Availablity : Dec. 2022

Pytorch debian packages for riscv are buggy for the moment.

Update : Pytorch is now working. See below
