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
}
```

1213: stm32: fix fmc-related build failures on some F4's r=Dirbaio a=Dirbaio
f413vh has a peripheral named `FSMC` but using the `FMC` regs. This might be a mistake? `@rmja`
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.

1205: stm32/rng Fix rng generation lock-up r=Dirbaio a=lucasgranberg
This PR fixes a problem where the device gets locked in case of rng errors.
The PR also includes a hack for stm32wl based devices where the more complicated RNG peripheral can get stuck on seed errors.
