Use a well known Kernel API is always a good idea than implement your own

struct l2cap_chan cames to create a clear separation between what
properties and data belongs to the L2CAP channel and what belongs to the
socket. By now we just fold the struct sock * in struct l2cap_chan as all
the channel info is struct l2cap_pinfo today.

In the next commits we will see a move of channel stuff to struct
l2cap_chan.

This patch adds automated creation of the local EIR data based on what
16-bit UUIDs are registered and what the device name is. This should
cover the majority use cases, however things like 32/128-bit UUIDs, TX
power and Device ID will need to be added later to be on par with what
bluetoothd is capable of doing (without the Management interface).

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.
