This is a little bit hacky, as it relies on rp2040-hal actually
using (and therefore linking) some defmt code when the defmt feature is
enabled.
However this solution has the advantage that it only affects
dev-dependencies and therefore has no impact on the board crates
themselves.
Closes#420
Current version of probe-run is 0.3.3, which uses defmt 0.3.2.
With a firmware using defmt 0.2, this causes the following error
message:
```
Error: defmt wire format version mismatch: firmware is using 0.2, `probe-run` supports 3
suggestion: `cargo install` a different version of `probe-run` that supports defmt 0.2
```
Therefore, upgrade defmt dependency, and also fix the linker script
in .cargo/config.
