Fixes the following warning:

[...]/pico-sdk/src/host/hardware_divider/include/hardware/divider.h:81:26: warning: operand of ?: changes signedness from 'int' to 'uint32_t' {aka 'unsigned int'} due to unsignedness of other operand [-Wsign-compare]
     return b ? (a / b) : -1;
                          ^~

The fix is to make the cast explicit, like hw_divider_divmod_u32 already does

Fixes the following warning:

```

going to merge anyway, but stylistically I would do (uint32_t)-1
