broadband-modem-mbim: add supported modes from CustomDataClass
Some modems (e.g. Telit FN990) reports 5G capabilities in CustomDataClass field of device-caps cid: take this into account when retrieving the supported modes.
Before the patch:
Modes | supported: allowed: 3g; preferred: none
| allowed: 4g; preferred: none
| allowed: 3g, 4g; preferred: none
| current: allowed: 3g, 4g, 5g; preferred: none
After the patch:
Modes | supported: allowed: 3g; preferred: none
| allowed: 4g; preferred: none
| allowed: 3g, 4g; preferred: none
| allowed: 5g; preferred: none
| allowed: 3g, 5g; preferred: none
| allowed: 4g, 5g; preferred: none
| allowed: 3g, 4g, 5g; preferred: none
| current: allowed: 3g, 4g, 5g; preferred: none
