Description
### Pre-flight checklist
- [x] I have searched existing issues and this is not a duplicate.
- [x] I have read the [Contributing Guidelines](https://github.com/CachyOS/linux-cachyos/blob/master/CONTRIBUTING.md).
- [x] I have verified the issue is reproducible with the latest available CachyOS kernel.
### Upstream / vanilla kernel check
I tested with a vanilla/upstream kernel and the issue does NOT reproduce there (CachyOS-specific bug)
### Kernel variant
linux-cachyos (EEVDF, Clang)
### System information (cachyos-bugreport.sh)

### Manual system information (if cachyos-bugreport.sh is unavailable)

### Bug description
When using a DualShock 4 (v1) controller via Bluetooth with the CachyOS kernel, `ehvz` reports polling rates of up to 20kHz (impossible for the DS4's puny BT chip and impossible for my beefy laptop). When playing, this results in input lag and eaten inputs.
```
# Test 1
Average for Wireless Controller: 11890Hz
Average for Wireless Controller Motion Sensors: 3164Hz
# Test 2
Average for Wireless Controller: 7653Hz
Average for Wireless Controller Motion Sensors: 8853Hz
```
I've tried with a Joy-Con, and it seems to work just fine (maybe a little slow?):
```
# Test 1
Average for Joy-Con (L): 61Hz
# Test 2
Average for Joy-Con (L): 57Hz
```
I've also tried with the latest Arch kernel, and polling rates with the DS4 look normal:
```
Average for Wireless Controller: 213Hz
Average for Wireless Controller Motion Sensors: 257Hz
```
Connecting the DS4 through USB works perfectly.
I'm wired, so Wi-Fi interference shouldn't be a problem.
### Steps to reproduce
1. Connect a DualShock (v1) controller through Bluetooth.
2. Open a terminal and run `sudo ehvz`.
3. Press some buttons and move sticks to register inputs.
4. Press CTRL+C to exit and see the output.
### Expected behavior
Polling rates of the DS4 < 1000Hz (1ms).
### Actual behavior
Impossible polling rates on DS4.

### Additional system information
Made sure to be using `hid-playstation` and not `hid-sony`.
