The LG LGSBWAC92/TWCM-K505D/EAT64454801/EAT64454802 (it goes by many
names) is a combo WiFi/Bluetooth module that's used in several models of
LG TVs. It uses the MediaTek MT7668AUN, which is already supported in
btusb, but this device has a non-MediaTek VID:PID pair so to get it to
work we just need to add it to the list of devices to probe.

Device from /sys/kernel/debug/usb/devices:

Changes from v2:
 - Specify device with USB_DEVICE again, to match the other "Additional
   MediaTek Bluetooth devices".
 - Add BTUSB_WIDEBAND_SPEECH and BTUSB_VALID_LE_STATES flags to the
   driver_info, since this device would otherwise have them applied were
   it not for the non-MediaTek vendor ID.

Changes from v1:
 - Added /sys/kernel/debug/usb/devices info.
 - Specify device with USB_DEVICE_AND_INTERFACE_INFO instead of just
   USB_DEVICE.
