List all possible valid CPU options.

An implementation for single CPU machines is still being discussed. A
solution proposed by Eduardo is this:
1) Change the default on TYPE_MACHINE to:
mc->valid_cpu_types = { TYPE_CPU, NULL };
This will keep the existing behavior for all boards.
2) mc->valid_cpu_types=NULL be interpreted as "no CPU model
except the default is accepted" or "-cpu is not accepted" in
machine_run_board_init() (I prefer the former, but both
options would be correct)
3) Boards like xlnx_zynqmp could then just do this:
static void xxx_class_init(...) {
mc->default_cpu_type = MY_CPU_TYPE;
/* Reason: XXX_init() is hardcoded to MY_CPU_TYPE */
mc->valid_cpu_types = NULL;
}
V5:
- Use cpu_model names
V4:
- Remove spaces
V3:
- Make variable static
V2:
- Don't use the users -cpu
- Fixup allignment
