545: Add adapter for implementing async traits for blocking types r=lulf a=lulf

This allows writing drivers relying on async traits, while still
functioning with implementations that already implement the embedded-hal
traits.

563: Initial ADC support for on STM32F1xx  r=Dirbaio a=sjoerdsimons

Add an ADC implementation for F1 based chips. Primarily tested using ADC1, proper functionality for ADC2 probably needs some extra work as it's mainly a slave and can't e.g. measure vrefint by itself.

559: USART DMA example for the STM32F7 r=Dirbaio a=olofwalker

This small PR adds the USART DMA write an example for the STM32F7. The example has been tested on a Nucleo-f767zi board.

558: Port buffered uart to v1 stm32 hardware r=Dirbaio a=DCNick3

#526 seems to suggest that it will be rewritten for DMA support, but I am not sure how to implement it and the port was quite straightforward, so here it is. It might be immediately useful before DMA version will be implemented

Note that I have not tested this on v2 hardware

Add infallible inherent methods, so that users don't have to import a trait, or `.unwrap()`.

544: Introduces split on the nRF Uarte r=Dirbaio a=huntc

A new `split` method is introduced such that the Uarte tx and rx can be used from separate tasks. An MPSC is used in an example to illustrate how data may be passed between these tasks.

The approach taken within the `Uarte` struct is to split into tx and rx fields on calling `Uarte::new`. These fields are returned given a call to `Uarte::split`, but otherwise, if that call isn't made, then the API remains as it was before.

Here's a snippet from a new example introduced:

```rust
#[embassy::main]
async fn main(spawner: Spawner, p: Peripherals) {
    // ...

    let uart = uarte::Uarte::new(p.UARTE0, irq, p.P0_08, p.P0_06, NoPin, NoPin, config);
    let (mut tx, rx) = uart.split();

    // ...

    // Spawn a task responsible purely for reading

    unwrap!(spawner.spawn(reader(rx, s)));

    // ...

    // Continue reading in this main task and write
    // back out the buffer we receive from the read
    // task.
    loop {
        if let Some(buf) = r.recv().await {
            info!("writing...");
            unwrap!(tx.write(&buf).await);
        }
    }
}

#[embassy::task]
async fn reader(mut rx: UarteRx<'static, UARTE0>, s: Sender<'static, Noop, [u8; 8], 1>) {
    let mut buf = [0; 8];
    loop {
        info!("reading...");
        unwrap!(rx.read(&mut buf).await);
        unwrap!(s.send(buf).await);
    }
}
```

543: Incrementally merge STM32 SPI versions, Part 3 r=Dirbaio a=GrantM11235

Notable changes:
- `SPE` is now disabled before `TXDMAEN` and `RXDMAEN` are disabled. This is the "mandatory" sequence for v2 and v3 (and maybe v1 as well, but I can't find it in the reference manual).
- v1's `write_dma_u8` now waits for idle and disables `TXDMAEN` after the transfer is complete, just like everything else.
