New issue by rubin55 on void-packages repository

https://github.com/void-linux/void-packages/issues/34554

Description:
### System

* xuname:  
  `Void 5.15.7_1 x86_64 AuthenticAMD notuptodate rF`
* package:  
  `linux5.15-5.15.7_1`

### Expected behavior
```
cat /boot/config-5.15.7_1 | grep CONFIG_BT_HCIBTUSB_MTK
CONFIG_BT_HCIBTUSB_MTK=m
```
### Actual behavior

```
cat /boot/config-5.15.7_1 | grep CONFIG_BT_HCIBTUSB_MTK
# CONFIG_BT_HCIBTUSB_MTK is not set
```

### Steps to reproduce the behavior

See above. This is simply a feature-request to enable `CONFIG_BT_HCIBTUSB_MTK` so that MediaTek based HCI bluetooth USB controllers start working (encountered this particular controller on my new AMD Ryzen 5880U based ThinkPad P14s).
