Convert tests/sdhci-test in first qgraph test node, sdhci-test. This test consumes an sdhci interface and checks that its function return the expected values. Note that this test does not allocate any sdhci structure, it's all done by the qtest walking graph mechanism Signed-off-by: Emanuele Giuseppe Esposito <e.emanuelegiuseppe@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
