[BUG] CPU speed missing on IBM Machine 8561 (IBM/s390x architecture)

### Read the FAQ first

- [x] I have checked the FAQ but the issue is not covered

### Description

Fastfetch doesn't show CPU speed of IBM Machine 8561 mainframe. Here is output of fastfetch:

And JSON output:
```
  {
    "type": "CPU",
    "result": {
      "cpu": "Machine 8561",
      "vendor": "IBM/S390",

        "max": 0
      },
      "coreTypes": [],
      "temperature": null
    }
  },
```

At same time, Neofetch show CPU speed correctly (5.2Ghz):

Here is output of /proc/cpuinfo:
