ahci: Adding basic functionality qtest.
Currently, there is no qtest to test the functionality of the AHCI functionality present within the Q35 machine type. This patch adds a skeleton for an AHCI test suite, and adds a simple sanity-check test case where we identify that the AHCI device is present, then disengage the virtual machine.
