mmc: core: Add mmc_retune_hold_now()
mmc_return_hold() / mmc_retune_release() are used around a group of commands to prevent re-tuning between the commands. Re-tuning can still happen before the first command. In some cases, re-tuning must be prevented entirely. Add mmc_retune_hold_now() for that purpose. It is added in preparation for CQE support where it will be used by CQE recovery.
