The Raspberry Pi 4 SDHCI hardware seems to automatically issue CMD12
after multiblock reads even when ACMD12 is disabled. This triggers
spurious interrupts after the data transfer is done with the following
message:
mmc1: Got data interrupt 0x00000002 even though no data operation was in progress.

mmc1: sdhci: ============================================
Enable SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12 to enable ACMD12 on multiblock
reads and suppress the spurious interrupts.
