e3174d7a99 STM32 SPI: Set clk-pin pull-up/-down to match spi clock polarity 
RM0394:

    40.4.6
    Communication formats
    ...
    The idle state of SCK must correspond to the polarity selected in the SPIx_CR1 register (by
    pulling up SCK if CPOL=1 or pulling down SCK if CPOL=0).

Merge #839 
839: Misc LoRaWAN improvements r=lulf a=timokroeger

Trying too get `embassy-lora` running on a [LoRa-E5 Dev Board](https://wiki.seeedstudio.com/LoRa_E5_Dev_Board/).
I can see the join message arriving in the The Things Network console but the device does not receive the accept message yet.
Opening this PR anyway because I think there are some nice things to decouple the lora crate from the nucleo board.

`@lulf` Could you test if this PR breaks your LoRa setup? Marking as draft for the time being.

8ba421f324 Do not use cfg_if for embedded-hal-async feature gates. 
Old code used `cfg_if!` because rustc still parses code inside disabled cfg's, and Rust stable at that time couldn't parse the new GAT where-clause location. This is not the case anymore.

61c666212f stm32wl: Do not require external SPI pins for SUBGHZ 
For the Seeed Studio Lora-E5 those pins conflict with the radio frontend control GPIOS (PA4 and PA5).

5ecbe5c918 embassy-stm32: Simplify time 
- Remove unused `MilliSeconds`, `MicroSeconds`, and `NanoSeconds` types
- Remove `Bps`, `KiloHertz`, and `MegaHertz` types that were only used
for converting to `Hertz`
- Replace all instances of `impl Into<Hertz>` with `Hertz`
- Add `hz`, `khz`, and `mhz` methods to `Hertz`, as well as
free function shortcuts
- Remove `U32Ext` extension trait

5085100df2 Add embassy-cortex-m crate. 
- Move Interrupt and InterruptExecutor from `embassy` to `embassy-cortex-m`.
- Move Unborrow from `embassy` to `embassy-hal-common` (nothing in `embassy` requires it anymore)
- Move PeripheralMutex from `embassy-hal-common` to `embassy-cortex-m`.

550da471be stm32: Remove OptionalPin 
The idea behind OptionalPin has a few problems:

- you need to impl the signal traits for NoPin which is a bit weird https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L413-L416
- you can pass any combination of set/unset pins, which needs checking at runtime  https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L130

The replacement is to do multiple `new` constructors for each combination of pins you want to take.
