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 after the next commit
is applied to check the CPU type in machine_run_board_init().

  ERROR:../hw/core/machine.c:1423:is_cpu_type_supported: \
  assertion failed: (model != NULL)
  Bail out! ERROR:../hw/core/machine.c:1423:is_cpu_type_supported: \
  assertion failed: (model != NULL)
  Aborted (core dumped)

Hide 'host' CPU model until KVM or HVF is enabled. With this applied,
the valid CPU models can be shown.

  qemu-system-aarch64: Invalid CPU type: cortex-a8
  The valid types are: cortex-a7, cortex-a15, cortex-a35, \
  cortex-a55, cortex-a72, cortex-a76, cortex-a710, a64fx, \
  neoverse-n1, neoverse-v1, neoverse-n2, cortex-a53,      \
  cortex-a57, max
