  KVM_GET_REG_LIST will dump all register IDs that are available to
KVM_GET/SET_ONE_REG and It's very useful to identify some platform
regression issue during VM migration.

Patch 1 enabled the KVM_GET_REG_LIST API in riscv and patch 2 added
the corresponding kselftest for checking possible register regressions.

Both patches were ported from arm64 and tested with Linux 6.4-rc1 on a
Qemu riscv virt machine.

  riscv: kvm: Add KVM_GET_REG_LIST API support
  KVM: selftests: Add riscv get-reg-list test
