Just updated to master and found out that the I2C config I implemented was replaced by this PR. Could anyone explain to me how PB8 and PB9 is supposed to be used on the L432KC/L031K6?

To put it simple: Where would I connect SCL and SDA? The config that was included as I2C config for these boards has the following connections defined:

```
        .scl_pin        = GPIO_PIN(PORT_B, 8),
        .sda_pin        = GPIO_PIN(PORT_B, 9),
```
