If CONFIG_MMCSD_SDIOWAIT_WRCOMPLETE is defined, the coremmc driver uses SD card's dat0 line to detect whether the sd card is still busy. This requires that the FPGA design using coremmc block wires dat0 line to some fabric irq; and configures CONFIG_MPFS_COREMMC_WRCOMPLETE_IRQNUM to point to that. Default for the irq number is 4.
