Gustavo F. Padovan d45dcef770 Bluetooth: Fix BT_L2CAP and BT_SCO in Kconfig
If we want something "bool" built-in in something "tristate" it can't
"depend on" the tristate config option.

Report by DaveM:

   I give it 'y' just to make it happen, for both, and afterways no
   matter how many times I rerun "make oldconfig" I keep seeing things
   like this in my build:

scripts/kconfig/conf --silentoldconfig Kconfig
include/config/auto.conf:986:warning: symbol value 'm' invalid for BT_SCO
include/config/auto.conf:3156:warning: symbol value 'm' invalid for BT_L2CAP

Bluetooth is low-cost, low-power, short-range wireless technology.
It was designed as a replacement for cables and other short-range
technologies like IrDA. Bluetooth operates in personal area range
that typically extends up to 10 meters. More information about
Bluetooth can be found at <http://www.bluetooth.com/>.
Linux Bluetooth subsystem consist of several layers:
Bluetooth Core (HCI device and connection manager, scheduler)
HCI Device drivers (Interface to the hardware)
SCO Module (SCO audio links)
L2CAP Module (Logical Link Control and Adaptation Protocol)
RFCOMM Module (RFCOMM Protocol)
BNEP Module (Bluetooth Network Encapsulation Protocol)
CMTP Module (CAPI Message Transport Protocol)
HIDP Module (Human Interface Device Protocol)
Say Y here to compile Bluetooth support into the kernel or say M to
compile it as module (bluetooth).
To use Linux Bluetooth subsystem, you will need several user-space
utilities like hciconfig and bluetoothd. These utilities and updates
to Bluetooth kernel modules are provided in the BlueZ packages. For
more information, see <http://www.bluez.org/>.
if BT != n
config BT_L2CAP
bool "L2CAP protocol support"
select CRC16
help
L2CAP (Logical Link Control and Adaptation Protocol) provides
connection oriented and connection-less data transport. L2CAP
support is required for most Bluetooth applications.
config BT_SCO
bool "SCO links support"
help
SCO link provides voice transport over Bluetooth. SCO support is
required for voice applications like Headset and Audio.
