Erick Shepherd be42e85091 mmc: Add quirk to disable DDR50 tuning
[ Upstream commit 9510b38dc0 ]

Adds the MMC_QUIRK_NO_UHS_DDR50_TUNING quirk and updates
mmc_execute_tuning() to return 0 if that quirk is set. This fixes an
issue on certain Swissbit SD cards that do not support DDR50 tuning
where tuning requests caused I/O errors to be thrown.
