[PATCH v4 22/33] target/microblaze: Implement microblaze_cpu_list()

[Gavin Shan]

Implement microblaze_cpu_list() to support cpu_list(). With this applied,
the available CPU model names, same to the CPU type names, are shown
as below.

  $ ./build/qemu-system-hppa -cpu ?
  Available CPUs:
    microblaze-cpu
