The replacement is `embassy-usb`. There's a WIP driver for stm32 USBD in #709,
there's no WIP driver for stm32 USB_OTG. This means we're left without
USB_OTG support for now.
Reason for removing is I'm going to soon remove `embassy::io`, and
USB uses it. I don't want to spend time maintaining "dead" code
that is going to be removed. Volunteers welcome, either to update
old USB to the new IO, or write a USB_OTG driver fo the new USB.
743: Add PLL config support for F2 r=Dirbaio a=Gekkio
- minor changes to make the F2 RCC API a bit more flexible
- low-level PLL config with assertions based on datasheet specs. It shouldn't be very difficult to later add a "reverse API" where you pass the clocks you want to a function and it generates a `PLLConfig` struct for you
- PLL API tested on my custom board with 12 MHz HSE as source for PLL to generate max clocks for SYSCLK/AHB/APB/APB1/PLL48
- the example *should* work but is untested since I don't have the Nucleo board 😞

SMI Ethernet PHYs all share a common base set of registers that can do
90% of all tasks. The LAN8742 driver used some vendor-specific
registers to check link negotiation status, but the need for that was
debatable, so I migrated it to a generic driver instead, anybody who
wants extra functionality can copy it and impl their own on top of it.
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
