NFC: LLCP raw socket support
This adds support for socket of type SOCK_RAW to LLCP. sk_buff are copied and sent to raw sockets with a 2 bytes extra header: The first byte header contains the nfc adapter index. The second one contains flags: - 0x01 - Direction (0=RX, 1=TX) - 0x02-0x80 - Reserved A raw socket has to be explicitly bound to a nfc adapter. This is achieved by specifying the adapter index to be bound to in the dev_idx field of the sockaddr_nfc_llcp struct passed to bind().
