Make mmc core able to use the blk-crypto framework for inline encryption. This patch introduces a pointer to struct keyslot_manager to struct mmc_host, and handles setting up the request_queue for devices using that keyslot_manager appropriately. It also inits struct mmc_request's inline encryption fields before it's passed to mmc_host::ops->request. Users of the core code in host/ (e.g. cqhci.c) should initialize the keyslot_manager in struct mmc_host appropriately, if they want to support inline encryption. They should also handle any inline encryption related work necessary when mmc_host::ops->request is called. This patch is only compile tested, as I don't have a device to actually test these patches.
