ahci: Add test_identify case to ahci-test.
Utilizing all of the bring-up code in pci_enable and hba_enable,
this test issues a simple IDENTIFY command via the HBA and retrieves
the response via the PIO receive mechanisms of the HBA.
Bugs: The DPS interrupt (Descriptor Processed Status) does not
currently get set. This will need to be adjusted in a future
patch series when the AHCI DMA pathways are reworked to allow
the feature, which may be utilized by OSX guests.
