This removes the hardcoded I2C address from the tests. The address is passed via QOSGraphEdgeOptions to i2c_device_create and stored in the QI2CDevice. The i2c_send and i2c_recv functions, along with their wrappers, therefore, can be changed to take a QI2CDevice rather than an adapter/address pair. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
