This makes the configuration more flexible and closer to the underlying
configuration register structure. For example, we could use HSI for the
system clock, but use HSE to output a clock with MCO.
* Add flash drivers for L0, L1, L4, WB and WL. Not tested for WB, but
should be similar to WL.
* Add embassy-boot-stm32 for bootloading on STM32.
* Add flash examples and bootloader examples
* Update stm32-data
714: add more clock options for l4 and l5 r=Dirbaio a=ant32
- added an assert so it panics if pll48div is not 48Mhz
- added MSI as a clock source for PLL
- removed hsi48 option for MCUs mentioned in l4 rcc presentation
- copied some code from l4 to l5, but don't have a way of testing it.

715: stm32/dac: Check proper channel r=Dirbaio a=michalsrb
Small fix. Otherwise it panics when trying to use channel 1 if channel 2 does not exist.

669: Add SDMMC v1 and SDIO support r=Dirbaio a=chemicstry
SDMMC v2 peripheral is an extension of SDMMC v1 (or SDIO) so I managed to reuse most of the code, with some cfg's.
Apart from small differeces in registers, the biggest change is that v2 uses internal DMA, while v1 has to use shared DMA peripheral. This makes code a bit uglier, because DMA channel for v1 has to be passed around. Not sure if it's possible to make it any cleaner.
This also adds `TransferOptions` structure to DMA, because SDMMC v1 requires setting peripheral flow control and burst transfers. Let me know if some alternative way would be prefered.
I tested this on STM32F429ZIT6 (with sd card) and STM32H745ZIT6 (with oscilloscope).
Depends on: https://github.com/embassy-rs/stm32-data/pull/130

673: Inline GPIO functions r=Dirbaio a=nviennot
All GPIO functions are monomorphized (per pin). Inlining these make the ROM smaller when using opt-level="z"

* 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
