The BR SMP fixed channel BR/EDR Security Manager (CID 0x0007) cannot be set in L2CAP Information Response. It is caused by the invalid fix channel definition used. Move macro `BT_L2CAP_BR_CHANNEL_DEFINE` to `l2cap_br_interface.h`, that the macro can be accessed in smp.c. And remove duplicated header file include `#include "classic/l2cap_ br_interface.h"` from smp.c. Define fixed channel, BR/EDR Security Manager (CID 0x0007), by using `BT_L2CAP_BR_CHANNEL_DEFINE`. Fix the smp L2CAP channel of BR cannot be found issue. Use `bt_l2cap_br_lookup_tx_cid` to get the BR SMP L2CAP channel instead of using `bt_l2cap_le_lookup_tx_cid`. Fix the invalid SMP L2CAP channel used when the BR smp failed. Signed-off-by: Lyle Zhu <lyle.zhu@nxp.com>
