992: (embassy-stm32): remove flash lock/unlock public API from stm32 flash r=lulf a=MathiasKoch
Instead, perform the unlocking and locking automatically on erase and write operations.
This makes the `embedded-storage` abstraction actually useable in libraries, while still keeping the flash peripheral locked the majority of the time.

960: Add non blocking Bxcan constructor r=Dirbaio a=andyblarblar
This PR adds a non-blocking constructor to the Bxcan Can wrapper struct. This allows for the creation of the Can periferal without blocking for a sync with the Can bus.

839: Misc LoRaWAN improvements r=lulf a=timokroeger
Trying too get `embassy-lora` running on a [LoRa-E5 Dev Board](https://wiki.seeedstudio.com/LoRa_E5_Dev_Board/).
I can see the join message arriving in the The Things Network console but the device does not receive the accept message yet.
Opening this PR anyway because I think there are some nice things to decouple the lora crate from the nucleo board.
`@lulf` Could you test if this PR breaks your LoRa setup? Marking as draft for the time being.

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.
* `MSIRGSEL = 1` was required for MSI accept the updated MSI range
* Reorder enable and clock switching to properly handle the jump from
the default 4MHz MSI to a higher MSI freuquency
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.

550da471be previously refactored the STM32
PWM logic in such a way to preclude use of non-contiguous channels (e.g.
channel 2 but not channel 1). Refactor it yet again to yet again allow
this sort of usage.
866: F4 flash fixes r=Dirbaio a=chemicstry
This discontinuous flash sector layout is too cursed and I left some mistakes in last PR. Erasing last sector did not work and it wasn't possible to erase between memory banks for 1MB dual-bank devices. So I changed the erase function to iterate over memory addresses (which is continuous) instead of sector numbers.
It should also be possible to implement erase across memory banks for H7, but it requires special handling for write too. I don't have an H7 to test now so left it as is.
I wasn't sure how to add tests to `embassy-stm32` and it seems that there are none, except for `subghz`, but no test runner? Anyway, I tested the `get_sector` on playground: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=13b59339fe6c70a3249e6183e81f869e
Also fixed erase alignment requirements on `Flash::blocking_erase()`, as it previously only checked alignment on size, but not on offsets.
P.S. the diff is a bit messed up, I recommend looking at files directly
