Register eMMC RPMB partition with the RPMB subsystem and provide an implementation for the RPMB access operations abstracting the actual multi step process. Add a callback to extract the needed device information at registration to avoid accessing the struct mmc_card at a later stage as we're not holding a reference counter for this struct. Taking the needed reference to md->disk in mmc_blk_alloc_rpmb_part() instead of in mmc_rpmb_chrdev_open(). This is needed by the route_frames() function pointer in struct rpmb_ops.
