l2cap_load() was added to trigger l2cap.ko module loading from the RFCOMM
and BNEP modules. Now that L2CAP module is gone, we don't need it anymore.

Actually doesn't make sense have these modules built separately.
The L2CAP layer is needed by almost all Bluetooth protocols and profiles.
There isn't any real use case without having L2CAP loaded.
SCO is only essential for Audio transfers, but it is so small that we can
have it loaded always in bluetooth.ko without problems.
If you really doesn't want it you can disable SCO in the kernel config.

Previous code set the channel type to NO_HT, but it

Some were indirectly set to NO_HT (zero), but I think
it's better to explicitly set it in case the enum ever
changes.  In cfg.c, it seems the channel-type was just
ignored (and thus always set to NO_HT).
