This fails the riscv qos-tests on s390x. My guess is that the new
IOMMU support has endianness bugs and fails on bigendian hosts.

The assertion failure is
ERROR:../tests/qtest/riscv-iommu-test.c:72:test_reg_reset: assertion
failed (cap & RISCV_IOMMU_CAP_VERSION == 0x10): (0 == 16)

but there are a lot of virtio errors before that so the
problem probably happened rather earlier.
