Changes since v1:
- Moved X86MachineClass related setup to x86_cpu_pre_plug [Eduardo],
  introduced kvm_hv_evmcs_available() to support the change.
- Droped PATCHes0-4 from v1 as x86_cpu_hyperv_realize() is not
  needed for the purpose of this series. I'll be sending them out
  as part of "KVM: expand Hyper-V features early" series after 5.11-rc1
  Linux release.

Original description:

This series is a part of the previously sent "[PATCH RFC v3 00/23] i386:
KVM: expand Hyper-V features early":
https://lists.gnu.org/archive/html/qemu-devel/2020-10/msg02443.html

We're not ready to merge the full patch set yet because the required
KVM capability is only queued for 5.11. We can, however, extract the
part providing 'hyperv=on' option to x86 machine types which is valuable
on its own.
