20032: boards/nucleo-l552ze: add PWM configuration r=benpicco a=krzysztof-cabaj

### Contribution description

This PR adds to the Nucleo-l552ze-q PWM configuration

### Testing procedure

Flash the board using `tests/periph/pwm` program. Check if you could, for example, change LED 
intensity using PWM. 

### Issues/PRs references

None.

* TIM[X] - is device,
* [Y] - describes used channel (indexed from 0), for example TIM2_CH1 is
* channel 0 in configuration structure (cc_chan - field),
