Documentation: KVM: Use unordered list for pre-init VGIC registers

The intent was to create a single column table, however the markup used
was actually for a header which led to docs build failures:

  Sphinx parallel build error:
  docutils.utils.SystemMessage: Documentation/virt/kvm/devices/arm-vgic-v3.rst:128: (SEVERE/4) Unexpected section title or transition.

Fix the issue by converting the attempted table to an unordered list.
