[RFC] External FCC unlock scripts
This merge request drops the built-in automatic FCC unlock procedures for all modules.
If the user wants to keep on using the ModemManager-provided unlock procedures, they must manually install the suggested unlock scripts from
/etc/ModemManager/fcc-unlock.d, make it root-owned, and update the file access mask to
0700. See https://modemmanager.org/docs/modemmanager/fcc-unlock
Alternatively, the user may also install a third party unlock tool provided by the laptop vendor or modem manufacturer itself.
The files installed under
/etc/ModemManager/fcc-unlock.d should not be automatically removed on package upgrades, so this manual procedure would be a one-time operation.
