EDR support

Hi guys,

I was checking the latest BlueZ source code and the kernel source code, 
and I noticed that by default EDR is disabled, when a dongle is detected 
net/bluetooth/hci_core.c initializes the packet types with DM1, DH1 and 
HV1, and then net/bluetooth/hci_event.c does it for DM3-5 DH3-5 and 
HV3-5, but it never initializes the 2DHx or 3DHx. Was it made on purpose 
or is it a bug in the code?

I just figured out how to help and try fixing it, but kernel hacking 
isn't an easy to do task, and would prefer to get professional advice first.
