428a4ba3f9 stm32/gpdma: clear all interrupts after reset. 
Reset doesn't clear them, this causes subsequent transfers to instantly
complete because the TC flag was set from before.

bbc81146ec BDMA: request stop after busy loop in blocking_wait(). 
Otherwise the channel cannot be used again, since CR.EN remains set
and the DMA channel registers are read-only while it is set.

921780e6bf Make interrupt module more standard. 
- Move typelevel interrupts to a special-purpose mod: `embassy_xx::interrupt::typelevel`.
- Reexport the PAC interrupt enum in `embassy_xx::interrupt`.

This has a few advantages:
- The `embassy_xx::interrupt` module is now more "standard".
  - It works with `cortex-m` functions for manipulating interrupts, for example.
  - It works with RTIC.
- the interrupt enum allows holding value that can be "any interrupt at runtime", this can't be done with typelevel irqs.
- When "const-generics on enums" is stable, we can remove the typelevel interrupts without disruptive changes to `embassy_xx::interrupt`.

1227: stm32/dma: fix spurious transfer complete interrupts r=Dirbaio a=pattop

DMA interrupts must be acknowledged by writing to the DMA_{L,H}IFCR
register.

Writing to the CR register is unnecessary as the channel (EN bit) is
disabled by hardware on completion of the transfer.
