879: Improve ADC configuration options r=Dirbaio a=chemicstry
This smooths out a few rough edges with ADC:
- Make `Resolution::to_max_count()` pub for all ADC versions. Useful if performing conversion manually.
- `VREF` and `VREFINT` were convoluted. `VREF` is an external voltage reference used for all ADC conversions and it is exposed as a separate pin on large chips, while on smaller ones it is connected to `VDDA` internally. `VREFINT` is an internal voltage reference connected to one of the ADC channels and can be used to calculate unknown `VREF` voltage.
- Add a separate `VREF_DEFAULT_MV`, equal to 3.3V, which is the usual supply voltage and should work for most simple cases.
- For an external voltage reference `set_vref()` can be used to set a known precise voltage.
- If no voltage reference is present, `VREFINT` calibration can be used to calculate unknown `VREF` voltage. If I understand correctly, this is only implemented for `adc_v3` (L4?), but is not currently exposed (private). If someone is interested, this can be fixed in separate PR.

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.

856: embassy-stm32/pwm: Generalize channel selection r=Dirbaio a=bgamari
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.

842: WIP: Make unborrow safe to use r=Dirbaio a=GrantM11235
The basic idea is that `Unborrow::unborrow` is now safe to call and returns an `Unborrowed<'a, T>` which impls `Deref` and `DerefMut`
```rust
/// This is essentially a `&mut T`, but it is the size of `T` not the size
/// of a pointer. This is useful if T is a zero sized type.
pub struct Unborrowed<'a, T> {
inner: T,
_lifetime: PhantomData<&'a mut T>,
}
```
## Todo
- [x] Update other crates
- [x] embassy-cortex-m
- [x] embassy-hal-common
- [x] embassy-lora
- [x] embassy-nrf
- [x] embassy-rp
- [x] embassy-stm32
- [x] Remove usage of the unsafe `into_inner` method if possible
- [x] Review and amend docs for `Unborrow` and `Unborrowed`

871: nrf/saadc: add type-erased AnyInput. r=Dirbaio a=Dirbaio
872: nrf/usb: prevent user code from constructing a PowerUsb directly. r=Dirbaio a=Dirbaio
PowerUsb must be constructed through `new()` so that it sets up the IRQ.
It must have at least one private field, otherwise user code can construct
it directly with `PowerUsb{}`.

874: Add inline attribute to embassy-rp async functions r=Dirbaio a=danbev
This commit adds the inline attribute to the recently added async gpio
functions. This is to enable cross-crate inlining and to be consistent
with the other functions implemented for Input and Flex.

868: Rename XXBusDevice to XXDevice. r=Dirbaio a=Dirbaio
I think the current naming is a bit odd, the EH traits are organized as "Bus" vs "Device", and XxxBusDevice is a Device (not a Bus, not both)
