3251a21fb7 Switch to crates.io embedded-hal, embedded-hal-async. 
This temporarily removes support for the async UART trait, since it's
not yet in embedded-hal-async.

e09bde9345 Add support for splitting stm32 usart into TX and RX 
* Keeps existing API for usart, but wraps it in Tx and Rx sub-types
* Adds split() method similar to nRF for getting indepdendent TX and RX
  parts
* Implements e-h traits for TX and RX types
* Add stm32h7 example

48f700b35c stm32 usart: Fix RX interrupt flag handling 
* On v1 interrupts cannot be cleared individually.
  Instead they are cleared implicitly by reading or writing DR (which we do now).
* Multiple error flags can be set at the same time:
  Handle them all in one go intstead of re-entering the ISR for each one so that
  we do not lose any error flags on v1 hardware.
* Wake when the RX buffer becomes full: This allows fast running chips to pull data
  from the buffer before receiving the next byte.

545: Add adapter for implementing async traits for blocking types r=lulf a=lulf

This allows writing drivers relying on async traits, while still
functioning with implementations that already implement the embedded-hal
traits.

cbff0398bb Add IRQ-driven buffered USART implementation for STM32 v2 usart (#356) 
* Add IRQ-driven buffered USART implementation for STM32 v2 usart

* Implementation based on nRF UARTE, but simplified to not use DMA to
  avoid complex interaction between DMA and USART.
* Implementation of AsyncBufRead and AsyncWrite traits
* Some unit tests to ring buffer
* Update polyfill version
* Update sub module to get usart IRQ fix
