[PATCH v5 21/31] target/xtensa: Use generic cpu_list()

[Gavin Shan <gshan@redhat.com>]

Before it's applied:

[gshan@gshan q]$ ./build/qemu-system-xtensa -cpu ?
Available CPUs:
  test_mmuhifi_c3
  sample_controller
  lx106
  dsp3400
  de233_fpu
  de212
  dc233c
  dc232b

After it's applied:

[gshan@gshan q]$ ./build/qemu-system-xtensa -cpu ?
Available CPUs:
  dc232b
  dc233c
  de212
  de233_fpu
  dsp3400
  lx106
  sample_controller
  test_mmuhifi_c3
