[PATCH v3 29/32] hw/arm/virt: Hide host CPU model for tcg

[Gavin Shan]

The 'host' CPU model isn't available until KVM or HVF is enabled.
For example, the following error messages are seen when the guest
is started with option '-cpu cortex-a8' on tcg.

  qemu-system-aarch64: Invalid CPU type: cortex-a8
  The valid types are: cortex-a7, cortex-a15, cortex-a35, cortex-a55,
                       cortex-a72, cortex-a76, a64fx, neoverse-n1,
                       neoverse-v1, cortex-a53, cortex-a57, (null),
                       max

Hide 'host' CPU model until KVM or HVF is enabled.
