[PATCH 05/10] hw/sd: sdhci: Use a QEMU-local no-busy IRQ quirk bit

[Bin Meng <bin.meng@processmission.com>]

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.
