Merge #18392 
18392: drivers/servo: reimplement with high level interface r=benpicco a=maribu

### Contribution description

The previous servo driver didn't provide any benefit over using PWM directly, as users controlled the servo in terms of PWM duty cycles. This changes the interface to provide a high level interface that abstracts the gory PWM details.

In addition, a SAUL layer and auto-initialization is provided.

### Testing procedure

The test application provides access to the servo driver via the `saul` shell command.

2022-08-02 22:12:45,343 # saul write 4 256
2022-08-02 22:12:45,346 # Writing to device #4 - servo

2022-08-02 22:12:45,351 # [servo] setting 0 to 6865 (255 / 255)
2022-08-02 22:12:45,354 # data successfully written to device #4
```

Each write resulted in the MG90S servo that I connected to move to the corresponding position.
