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.

935: Remove generic const expressions from embassy-boot r=lulf a=lulf
* Remove the need for generic const expressions and use buffers provided in the flash config.
* Extend embedded-storage traits to simplify generics.
* Document all public APIs
* Add toplevel README
* Expose AlignedBuffer type for convenience.
* Update examples

* Update examples
Call `config()` only once at construction not with every RX and TX operation.
The Lora-E5 only supports HP mode, use that instead.
The nucleo board supports both HP and LP and should continue to work.
The Seeed Studio Lora-E5 module only has two control pins.
With the `RadioSwitch` trait the user can implement any method required
by the module/board to control the TX/RX direction of the radio frontend.
* Interrupt handler only triggers a waker:
Do the actual interrupt processing which involves SUBGHZ SPI coms in the task.
* Do not require a static state for the constructor.
* Remove unsafe from construcor.
913: (embassy-rp): Add DMA implementation r=Dirbaio a=MathiasKoch
This PR adds everything necessary to do peripheral to memory DMA & memory to memory DMA operations.
It also adds async UART read & write, powered by DMA

This fixes the WASM support which was failing due to missing
critical-section implementation. This also upgrades the bindgen
dependency and ensures that tooling works.
It was only useful for doing #[embassy_executor::main(config = "config()")]`. Now that
it's gone, it makes more sense to build the config in main directly.
896: Implement I2C pullup configuration r=lulf a=chemicstry
I wasn't sure if I should put frequency into config struct, so left it separate as in SPI periph.
Also added Copy derives to gpio types, not sure why they weren't?
