Merge #429 #431
429: nrf/uarte: do not use WFE on drop. r=Dirbaio a=Dirbaio
- It disturbs other stuff that uses WFE/SEV in the system. I ran into issues with this.
- It needs the irq handler to check for RXTO/TXSTOPPED errors, which makes it slower.
431: interrupt: transmute instead of steal. r=Dirbaio a=Dirbaio
That steal method has a TAKEN=true write [here](https://github.com/rust-embedded/cortex-m/blob/6b013138b734b9bbeb24a345f75d2bcc1c69fa8d/src/peripheral/mod.rs#L180).
This is not zero cost, we don't want it. Transmute instead, which is zero cost.
