1480: stm32: Async flash support for F4 r=rmja a=rmja
This PR depends on https://github.com/embassy-rs/embassy/pull/1478.
It adds async write/erase operations to the F4 series based on the work in https://github.com/embassy-rs/embassy/pull/870 but aligned to the new flash regions.
If one considers the entire `Flash` then nothing has changed other than the async operations have been added.

1475: Add YieldingAsync adapter r=Dirbaio a=rmja
This PR calls `yield_now()` for long blocking `NorFlash` read and erase operations.
The motivation for this change is to allow for other tasks on the same executor to get something done between these long running operations, for example a task that feeds a watchdog. This will allow the watchdog to have a timer relative to e.g. one sector erase, instead of all sector erase.
1478: stm32: Minor fixes in flash regions for F4 dual bank layout r=Dirbaio a=rmja
This PR has the following fixes:
* Ensure that `FlashRegion` instances can only be created within the embassy-stm32 crate.
* Remove `Drop` trait for `AltFlashLayout`, as it is hard to use, as one cannot take the individual regions out from the struct. Instead of going back to single bank mode on `Drop`, we instead transition to single bank mode when calling `Flash::into_regions()`.
* Add missing `otp_region` to the dual bank layout and implement `NorFlash` for the alternate regions.
1482: Add ConcatFlash utility r=Dirbaio a=rmja
This PR adds a `ConcatFlash` utility that can be used to concatenate two `NorFlash` flashes. This is especially useful when concatenating multiple flash regions with unequal erase size.

1340: Add I2S for f4 r=Dirbaio a=xoviat
This is only for f4, but it puts us equal to or ahead of the standard rust hal.

1457: TL Mbox read and write for stm32wb r=xoviat a=OueslatiGhaith
Hello,
This pull request is related to #1397 and #1401, inspired by #24, built upon the work done in #1405 and #1424, and was tested on an stm32wb55rg.
This pull request aims to add read and write functionality to the TL mailbox for stm32wb microcontrollers

1454: stm32f0 flash implementation r=Dirbaio a=jp99
i've copied and modified the f3 implementation and it seems to be working.

Clear and report the error flags one by one and pop the data byte only
after all error flags were handled.
For v1/v2 we emulate the v3/v4 behaviour by buffering the status
register because a read to the data register clears all flags at once
which means we might loose all but the first error.
1424: add TL maibox for stm32wb r=xoviat a=OueslatiGhaith
Hello,
This pull request is related to #1397 and #1401, inspired by #24, build upon the work done in #1405, and was tested on an stm32wb55rg.
This pull request aims to add the transport layer mailbox for stm32wb microcontrollers. For now it's only capable of initializing it and getting the firmware information

This flag for example permits the following clock tree
configuration on stm32f103r8
let mut config = Config::default();
config.rcc.hse = Some(Hertz(16_000_000));
config.rcc.sys_ck = Some(Hertz(72_000_000));
config.rcc.pclk1 = Some(Hertz(36_000_000));
config.rcc.pclk2 = Some(Hertz(72_000_000));
config.rcc.pllxtpre = true;
Init fails if pllxtpre is false.
