the Portenta H7 uses the same chip as the GIGA R1 WiFI - but I wonder if vos1 is too high a voltage given

```rust
    #[must_use]
    pub fn vos0(mut self, _: &SYSCFG) -> Self {
        self.target_vos = VoltageScale::Scale0;
        self
    }
    /// Configure Voltage Scale 1. This is the default configuration
    #[must_use]
    pub fn vos1(mut self) -> Self {
        self.target_vos = VoltageScale::Scale1;
        self
    }
```
