SDHCI_QUIRK_NO_BUSY_IRQ was copied from Linux with its bit number unchanged. The quirk mask is internal to QEMU: it is neither visible to guests nor part of migration state. Mirroring Linux therefore provides no compatibility benefit and constrains local allocations.
Move it to bit zero so QEMU can allocate SDHCI quirks sequentially in its own namespace.
