inputmodule: Show location

Otherwise if you have two LED matrices, you don't know which one's
which.

```
> framework_tool --versions
[...]
LED Matrix
  Firmware Version: 0.2.0
  Location: [X] [ ] [ ]       [ ] [ ]
LED Matrix
  Firmware Version: 0.2.0
  Location: [ ] [ ] [ ]       [ ] [X]
Laptop 16 ANSI Keyboard
  Firmware Version: 0.1.6
  Location: [ ] [X] [ ]       [ ] [ ]
[...]
```
