672: Reset peripherals on enable r=chemicstry a=chemicstry
Add reset on initialization to peripherals that did not have it before. This fixes problems when same peripheral is reinitialized at runtime multiple times.
Some exceptions:
- ADC: all ADCs share a single reset
- DCMI: does reset before enable - couldn't find anything about the order in the reference manual. Just keep it if it works?
I also fixed safety issues where global RCC registers where accessed without critical section.

670: Make UART futures Send r=Dirbaio a=chemicstry
This is a quick fix to make `Uart` futures implement `Send`.
Previously they were `!Send`, because pointer to the data register was held across an await point. Simple rearrange fixes the issue.

661: Add support for splitting stm32 usart into TX and RX r=lulf a=lulf
* 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

662: stm32: Finish unifying spi versions r=Dirbaio a=GrantM11235
Notable changes:
- `set_word_size` is always called before disabling SPE. This is important because `set_word_size` may or may not re-enable SPE.
- The rx buffer is flushed on v1 as well. I don't know if this is required.
- All functions are now generic over word size
