667: Remove duplicate stm32-metapac/src/common.rs with chiptool r=Dirbaio a=nviennot

There's a duplicate file common.rs with the chiptool crate. This PR makes the source of truth the one in chiptool.

This PR is a good pair with https://github.com/embassy-rs/chiptool/pull/4

662: stm32: Finish unifying spi versions r=Dirbaio a=GrantM11235

Notable changes:
- `set_word_size` is always called before disabling SPE. This is important because `set_word_size` may or may not re-enable SPE.
- The rx buffer is flushed on v1 as well. I don't know if this is required.
- All functions are now generic over word size

640: Skip EasyDMA slice location check for empty slices and copy data if necessary r=Dirbaio a=TilBlechschmidt

As discussed, this PR makes the following changes:
- Ignore pointer location of zero-length slices (fixes #631)
- Change default functions so they copy the tx buffer if it does not reside in RAM
- Introduce new variants for `write`, `transfer`, and their blocking versions which fails instead of copying
- Add documentation about the motivation behind all these variants
<img width="984" alt="image" src="https://user-images.githubusercontent.com/5037967/155415788-c2cd1055-9289-4004-959d-be3b1934a439.png">


Remaining TODOs:

- [x] Change copying behaviour for other peripherals
    - [x] TWI
    - [x] UART
- [x] Add module-level documentation regarding EasyDMA and `_from_ram` method variants

`@Dirbaio` it probably makes sense for you to review it now before I "copy" over the changes to the other two peripherals.

648: Fix nRF Saadc continuous sampling r=Dirbaio a=huntc

Starting the sampling task prior to starting the SAADC peripheral can lead to unexpected buffer behaviour with multiple channels. We now provide an init callback at the point where the SAADC has started for the first time. This callback can be used to kick off sampling via PPI.

We also need to trigger the SAADC to start sampling the next buffer when the previous one is ended so that we do not drop samples - the major benefit of double buffering.

Given these additional tasks, we now simplify the API by passing in the TIMER and two PPI channels.

As a bonus, we provide an async `calibrate` method as it is recommended to use before starting up the sampling.

The example has been updated to illustrate these new features along with the simplified API.

The changes here have been tested on my nRF52840-DK.

656: stm32: Refactor DMA interrupts r=Dirbaio a=GrantM11235

Previously, every dma interrupt handler called the same `on_irq`
function which had to check the state of every dma channel.

Now, each dma interrupt handler only calls an `on_irq` method for its
corresponding channel or channels.
