mmc: sdhci-iproc: suppress spurious interrupt with Multiblock read
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.
