mrvl/sdsd8997_combo_v4.bin, from linux-firmware GIT, 16.92.21.p137
version. From an off-list chat with Rafael he confirmed me that this is
what he used for testing.

This is already implemented. From mwifiex_ret_get_hw_spec()

```
        if (adapter->key_api_major_ver != KEY_API_VER_MAJOR_V2)
                adapter->host_mlme_enabled = false;
```

To me the patch is ok.
