1225: nrf: rename UARTETWISPIn -> SERIALn r=Dirbaio a=Dirbaio
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.

1226: embassy-net: Implement flush for TcpSocket r=Dirbaio a=kbleeke
Implements flush for TcpSocket by checking the send queue.
Flushing is implemented by checking if smoltcp's send_queue/tx_buffer is empty. The flush is completed when all outstanding octets are acknowledged. Smoltcp wakes the send waker [here](https://docs.rs/smoltcp/latest/src/smoltcp/socket/tcp.rs.html#1712) when ACKs are processed and data is removed from the send buffer. So we can re-check in our flush implementation, if the buffer is now empty.

1170: nrf: add support for UICR configuration. r=Dirbaio a=Dirbaio
- 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.
TODO: test
- [x] nrf52 rev1
- [x] nrf52 rev3
- [x] nrf53
- [x] 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.

1221: examples/stm32wb: do not reserve words at start of RAM. r=Dirbaio a=Dirbaio
They're used to communicate from the app to ST's OTA bootloader. See AN5247.
This bootloader is optional, must be flashed by the user, and requires changing the FLASH start address as well, so the current memory regions still require modifications to use it. Therefore there's no point in reserving these words.
Thanks `@adamgreig` for investigating the purpose.

1219: stm32/sdmmc: Fix SDIOv1 writes r=Dirbaio a=chemicstry
This fixes writes on sdmmc v1 (SDIO). I'm pretty sure I tested writes in #669, but maybe I was just lucky or I just forgot.
There were two problems:
- Writes require DMA FIFO mode, otherwise SDIO FIFO is under/overrun depending on sdio/pclk2 clock ratio.
- Hardware flow control is broken for sdmmc v1 (I checked F1 and F4 erratas). This causes clock glitches above 12 MHz and results in write CRC errors.

1215: Add clone to embassy_rp::gpio::Level r=Dirbaio a=Slushee-a
Allows you to wite a cleaner state change detector. Example:
```rs
let mut button_state: Level = Level::Low;
let mut prev_button_state: Level = button_state;
loop {
button_state = button.get_level();
if prev_button_state != button_state {
led.set_level(button_state); // Takes ownership of button_state.
}
prev_button_state = button_state; // Can't be done since the ownership has been moved.
// Adding Clone makes this code possible
}
```

Fix build for now, we can investigate later if the regs are OK.

1210: nrf/qspi: do not panic when canceling futures. r=Dirbaio a=Dirbaio
QSPI can't cancel DMA transfers. Before we'd panic on cancel, now we blocking-wait instead.
Blocking is not great, but it's better than panicking, especially when using code that's hardware-agnostic through the embedded-storage traits.

1209: Time: Add from_hz function for Duration. r=Dirbaio a=CBJamo
I found myself doing things like this
```rust
let rate_us = 1_000_000 / rate_hz;
let mut ticker = Ticker::every(Duration::from_micros(rate_us));
```
Several times, and figured it was worth adding a little convenience function to handle that. This also makes the calculation const, which is a nice little upside. The compiler might have been doing that already, but this makes sure.
Speaking of const, would it be better to give hz as a float? Obviously we'd want to avoid that at runtime since many targets don't have a fpu, but if it's at compile time that doesn't matter and a float may be more ergonomic.
