The stack reads its own descriptors to figure out which endpoints
are used in which alt settings, and enables/disables them as needed.
The ControlHandler has a callback so it can get notified of alternate
setting changes, which is purely informative (it doesn't have to do anything).
727: Switch to crates.io embedded-hal, embedded-hal-async. r=Dirbaio a=Dirbaio
This temporarily removes support for the async UART trait, since it's
not yet in embedded-hal-async.

713: Bootloader external flash r=lulf a=lulf
Includes e-s and e-s-a impls for nrf QSPI
WIP: Working on testing it.
Co-authored-by: Ulf Lilleengen <ulf.lilleengen@gmail.com>
* Add FlashProvider and FlashConfig traits to define flash
characteristics
* Use traits in bootloader to retrieve flash handles and for
copying data between flash instances
* Add convenience implementations for using a single flash instance.
723: Add embedded-storage trait impls for QSPI r=Dirbaio a=lulf
* Adds implementations of embedded-storage and embedded-storage-async
for QSPI
* Add blocking implementations of QSPI
* Use blocking implementation in new() and embedded-storage impls
* Use async implementation in embedded-storage-async impls
* Add FLASH_SIZE const generic parameter
* Own IRQ in Qspi instance to disable it on drop.

720: USB: New builder API r=Dirbaio a=Dirbaio
usb: improved descriptor building API
The same API call allocates interfaces/endpoints/etc and writes their descriptors.
This means less API calls, and less possibility to screw things up.
DescriptorWriter is now private.

This means less API calls, and less possibility to screw things up.
DescriptorWriter is now private.
- Renamed structs to HidReaderWriter, HidReader, HidWriter.
- Removed unused const generics on `State`.
- Simplified generics on `HidReaderWriter`.
The class type previously was `HidClass<D, Driver<'d, USBD>, ReportReader<'d, Driver<'d, USBD>, OUT_N>, IN_N>`
It's now `HidClass<D, Driver<'d, USBD>, IN_N, OUT_N>`. Note that the driver type `Driver<'d, USBD>` is no longer repeated.
- Constructors are now: `HidWriter::new()` for IN-only, `HidReaderWriter::new()` for IN+OUT. No complicated bounds.
- HidReaderWriter has all the methods from HidReader, HidWriter.
711: Add DeviceStateHandler, DeviceCommand channel, and remote wakeup support r=Dirbaio a=alexmoon
Apologies for the size of this PR. Once I started getting into the Vbus power management side of my device I found a couple of areas of functionality missing from embassy-usb. Specifically, I need the application to be able to respond to changes in the USB device state in order to properly control the amount of power I'm drawing from Vbus. I also wanted to enable remote wakeup support for my device.
In order to enable device state monitoring, I've created a `DeviceStateHandler` trait and made it possible to pass in an optional reference a handler implementing that trait when creating the `UsbDeviceBuilder`.
Remote wakeup required a way to send commands to the bus which is exclusively owned by the `UsbDevice::run` method. This is the same problem we were discussing for enabling/disabling the device on Vbus power events. My solution is to allow an optional `Channel` to be provided to the `UsbDeviceBuilder` (via `UsbDeviceBuilder::new_with_channel`), allowing the application to send commands into the `run` method. Right now it supports enable, disable and remote wakeup commands.
Since there's now a way to dynamically enable and disable the device, I also added `Config::start_enabled` to control whether or not the `UsbDevice` should start in the enabled state. That also allowed me to make `UsbDeviceBuilder::build` sync again and move enabling the bus into `UsbDevice::run`.
This led to a few driver changes:
1. `Driver::enable` became `Driver::into_bus`
2. `Bus::enable`, `Bus::disable`, and `Bus::remote_wakeup` were added
3. I removed `Bus::reset`, `Bus::suspend`, and `Bus::resume` because they were only ever called based on the result of `Bus::poll`. It made more sense to me to have `Bus::poll` handle the driver-specific state management itself.
I've updated the `usb_hid_keyboard` example to take advantage of all these additional features.
Let me know what you think.
Thanks!

714: add more clock options for l4 and l5 r=Dirbaio a=ant32
- added an assert so it panics if pll48div is not 48Mhz
- added MSI as a clock source for PLL
- removed hsi48 option for MCUs mentioned in l4 rcc presentation
- copied some code from l4 to l5, but don't have a way of testing it.

694: Add select, select3, select4. r=Dirbaio a=Dirbaio
The difference with those from the `futures` crate is they don't return the other partially-run futures, so they can work with `!Unpin` futures which makes them much easier to use.

715: stm32/dac: Check proper channel r=Dirbaio a=michalsrb
Small fix. Otherwise it panics when trying to use channel 1 if channel 2 does not exist.

699: Add ADC support for H7 r=Dirbaio a=matoushybl
Seems to work on H743, ADC1 works fine, but ADC3 has different ADC_COMMON block which stm32-data does't yet support, so measuring VREFINT or TEMP doesn't work. I'd like to discuss how adding support for the different ADC_COMMON could be done.

712: Add types for channel dynamic dispatch r=lulf a=lulf
* Add internal DynamicChannel trait implemented by Channel that allows
polling for internal state in a lock safe manner and does not require
knowing the channel size.
* Existing usage of Sender and Receiver is preserved and does not use
dynamic dispatch.
* Add DynamicSender and DynamicReceiver types that references the
channel using the DynamicChannel trait and does not require the const
generic channel size parameter.
Having the ability not know the channel size is very convenient when you don't want to change all of your channel using code when tuning the size. With this change, existing usage can be kept, and those willing to pay the price for dynamic dispatch may do so.

Originally #698, got overwritten in a rebase I think.
