CONFIG_MMC_SPEED_MODE_SET should be enabled. The required speed mode is
passed as the index from the following list.
0 - MMC_LEGACY
1 - MMC_HS
2 - SD_HS
3 - MMC_HS_52
4 - MMC_DDR_52
5 - UHS_SDR12

CONFIG_MMC_SPEED_MODE_SET should be enabled. The requested speed mode is
passed as a decimal number according to the following table:
