mmc: block: Delete mmc_access_rpmb()
This function is used by the block layer queue to bail out of requests if the current request is towards an RPMB "block device". This was done to avoid boot time scanning of this "block device" which was never really a block device, thus duct-taping over the fact that it was badly engineered. This problem is now gone as we removed the offending RPMB block device in another patch and replaced it with a character device.
