CI wasn't happy because of a transitive dependency on a version of the riscv crate that had been yanked.
Also removed an import from UART that wasn't used that was triggering a clippy warning - it can be re-added when it is used.
We aren't using panic-halt in our examples since we have a serial panic print, so drop that dep.
Disabled warnings on lack of # Safety comments on SPI pin traits - will want to move them to sealed traits in the future anyway.
