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

This is useful in some cases where the surrounding circuit
for some reason inverts the UART signal, for instance if you're talking
to a device via an optocoupler.
