mmc: sdhci-of-arasan: Add "SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12" quirk.
Arasan controller supports AUTO CMD12, this patch adds
"SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12" quirk to enable auto cmd12
feature.
By using auto cmd12 we can also avoid following error message
"Got data interrupt even though no data operation in progress"
