  target/riscv: Support the Virtual Instruction fault (2020-08-25 09:11:36 -0700)

----------------------------------------------------------------
This pull request first adds support for multi-socket NUMA RISC-V
machines. The Spike and Virt machines both support NUMA sockets.

This PR also updates the current experimental Hypervisor support to the
v0.6.1 spec.
