Polling SDIO_CCCR_INTx could create a fake interrupt with Marvell SD8797 card. Add a quirk to handle this case. The fixup here is to issue a dummy CMD52 read to function 0 register 0xff, and this dummy read must be right after SDIO_CCCR_INTx is read. Patch has been verified on a dw_mmc controller (Samsung Chromebook) with MMC_CAP_SDIO_IRQ disabled.
