cpu: Add generic cpu_list()

Add generic cpu_list() to replace the individual target's implementation
in the subsequent commits. Currently, there are 3 targets with no cpu_list()
implementation: microblaze and nios2. With this applied, those two targets
switch to the generic cpu_list().

[gshan@gshan q]$ ./build/qemu-system-microblaze -cpu ?
Available CPUs:
  microblaze-cpu

[gshan@gshan q]$ ./build/qemu-system-nios2 -cpu ?
Available CPUs:
  nios2-cpu
