855: PDM microphone support for nrf r=Dirbaio a=pbert519
PDM microphones have a long startup phase, therefore the driver samples continuously and only switches the target buffer if the user requests sampling.

This commit removes some of the code duplication for UarteWithIdle at the expense of requiring a split. As the example illustrates though, this expense seems worth the benefit in terms of maintenance, and the avoidance of copying over methods. My main motivation for this commit was actually due to the `event_endtx` method not having been copied across.
958: Implement proper `Drop` for `BufferedUarte` r=lulf a=ZoeyR
The drop method in `BufferedUarte` was prone to hanging indefinitely and also didn't actually disable the peripheral. I mostly copied over the drop method from `Uarte` with some modifications since `BufferedUarte` could have a transmit lasting indefinitely.

936: Add split() method to BufferedUarte in embassy-nrf r=ZoeyR a=ZoeyR
I haven't completed testing this yet. I'm creating this PR early so that I can get corrected if I went way off course.
This PR adds a `split()` method to `BufferedUarte` as discussed on matrix.

938: Do not use cfg_if for embedded-hal-async feature gates. r=Dirbaio a=Dirbaio
Old code used `cfg_if!` because rustc still parses code inside disabled cfg's, and Rust stable at that time couldn't parse the new GAT where-clause location. This is not the case anymore.

Ensures that nRF saadc sampling is stopped and is awaited prior to exiting the two sampling methods. Not doing so causes a potential power drain and the potential for dropped buffer writes when having finished continuous sampling.
876: Add defmt support to embassy-embedded-hal errors r=Dirbaio a=matoushybl
`defmt::unwrap!()` should now work with shared buses. I tested it only with I2C as I don't have SPI in the target project.
