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 USB VID so to get it to work
we just need to add it to the list of devices to probe.

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