The stingray SDHCI hardware supports ACMD12 and automatically
issues after multi block transfer completed.

If ACMD12 in SDHCI is disabled, spurious tx done interrupts are seen
on multi block read command with below error message:

Got data interrupt 0x00000002 even though no data
operation was in progress.

This patch uses SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12 to enable
ACM12 support in SDHCI hardware and suppress spurious interrupt.
