feat(sdmmc): Concurrent use of SDMMC peripheral

Browse Source 
Host and device (card, etc.) initialization is not thread-safe.
After initialization transactions are serialized and guarded by mutex.
Changed `SDMMC_HOST_DEFAULT()` default deinit function to `sdmmc_host_deinit_slot`
which has a slot number as argument.
