1369: Lora AFIT r=Dirbaio a=Dirbaio
Extracted out of #1367
Probably we should wait until `rust-lorawan` is merged+released?

1371: RTC r=Dirbaio a=xoviat
This adds RTC for most of the stm32 chips. Nearly all of the work was not done by me, but I took it the last bit by disabling the chips that weren't working. I think it would be easier to enable them in future PRs if requested.
1374: stm32: remove TIMX singleton when used on timer driver r=Dirbaio a=xoviat
After multiple ways of looking at this, this is the best solution I could think of.

1372: rp: add division intrinsics r=Dirbaio a=pennae
rp2040-hal adds division intrinsics using the hardware divider unit in the SIO, as does the pico-sdk itself. using the hardware is faster than the compiler_rt implementations, and more compact too.
since embassy does not expose the hardware divider in any way (yet?) we could go even further an remove the state-saving code rp2040-hal needs, but that doesn't seem to be worth it.

Adds the i2s pll on some f4 micros.
1361: Executor: Replace unnecessary atomics in runqueue r=Dirbaio a=GrantM11235
Only the head pointer needs to be atomic. The `RunQueueItem` pointers are only loaded and stored, and never concurrently

1359: Make Hertz constructors `const` r=Dirbaio a=sgoll
This PR makes `Hertz` associated functions `hz()`, `khz()`, `mhz()` and their unassociated variants `const`, allowing `Hertz` to be used more easily in constant values:
```rust
const FREQ1: Hertz = Hertz::khz(120);
const FREQ2: Hertz = mhz(1);
```
This follows the pattern used for similar types such as `Duration` and `Instant`, from `embassy-time/src/duration.rs` and `embassy-time/src/instant.rs`, respectively.

1353: Add empty test binary for riscv r=Dirbaio a=royb3
As discussed with `@Dirbaio,` this empty test binary should cause a build to fail when it is not possible to build or link a riscv binary.
