This property is used in the MMIfaceModem to flag whether the SIM hot
swap setup has been performed or not. The flag is now moved to the
iface-specific private context.
The property was also used in AT-based modems, so that implementations
supporting the SIM hot swap via AT URCs could flag the upper layers
whether the enabling of the feature was done correctly or not, and if
so, create and keep the AT ports context open. But this feature only
made sense in AT-based modems, i.e. an MBIM modem that detects SIM hot
swaps via MBIM indications exclusively should not require the AT ports
context open for anything. The check in the MMBroadbandModem object
has therefore been removed, and the logic will be updated so that it
only applies to AT-based modems.
We're not going to implement all XMM shared operations from the shared
utils, as the newer Intel modems support the new operations in the
Microsoft MBIM Extensions.
Just inherit the GNSS management capabilities.
