The stm32_sdmmc variant has build-in support for datatimeout for R1B requests. If a corresponding IRQ is raised, this triggers the DPSM to stay busy and remains in a non-functional state. Only a reset can bring it back to a functional state. Because a reset must be issued from non-atomic context, let's defer this to be managed from a threaded IRQ handler. Besides the reset, the threaded handler also calls mmc_request_done(), to finally complete the request.
