1262: bump embedded-storage-async to 0.4 r=Dirbaio a=mehmetalianil
I just haven't found a way to revert the altered stm-metapac contents due to building.

So we're going to do just that!
- BufferedUarte is lock-free now. No PeripheralMutex.
- The "restart DMA on line idle to flush it" hack is GONE. This means
- It'll work correctly without RTS/CTS now.
- It'll have better throughput when using RTS/CTS.
The UARTETWISPIn naming is quite horrible. With the nRF53, Nordic realized this
and renamed the interrupts to SERIALn. Let's copy that for our peripheral names, in nrf53 and nrf91.
If the user requests some configuration, but UICR is already programmed
to something else, detect this and warn the user.
We don't do it for the debug port settings, because if they are wrong
then the user will simply not be able to read debug logs.
- APPROTECT enable/disable. Notably this fixes issues with nrf52-rev3 and nrf53 from locking itself at reset.
- Use NFC pins as GPIO.
- Use RESET pin as GPIO.
NFC and RESET pins singletons are made available only when usable as GPIO,
for compile-time checking.
Obtaining the current WDT config is important so that we do not have to duplication configuration around the place. A constructor method has been introduced that returns WDT config in accordance with how the register is presently configured. The bootloader example has also been updated to show the watchdog can be obtained and used.
It's a perfectly fine thing to do, should be just a noop. Erroring is
really annoying when you're writing a payload to uart that might
be zero-length or not.
1069: GPIOTE InputChannel with mutable reference. r=Dirbaio a=Ardelean-Calin
Adding these changes enables us to define a channel using a mutable reference to `GPIOTE_CH(n)`, similar to how we can do with other drivers. So instead of using:
```rust
let p = embassy_nrf::init(config);
let freq_in = InputChannel::new(
p.GPIOTE_CH0,
Input::new(&mut p.P0_19, embassy_nrf::gpio::Pull::Up),
embassy_nrf::gpiote::InputChannelPolarity::HiToLo,
);
```
we can use:
```rust
let p = embassy_nrf::init(config);
let freq_in = InputChannel::new(
&mut p.GPIOTE_CH0,
Input::new(&mut p.P0_19, embassy_nrf::gpio::Pull::Up),
embassy_nrf::gpiote::InputChannelPolarity::HiToLo,
);
```
therefore not giving ownership to GPIOTE_CH0.
