ata_piix: convert to prepare - activate initialization
ata_piix requires more configuration during initialization than most other SFF compliant controllers and one-go initialzation with ata_pci_one() is too rigid. This patch converts ata_piix to use two step prepare - activate initialization used by other more advanced controllers. This conversion brings the happy side effect of enabling PCI device before accessing PCI configuration registers. Other than that, there shouldn't be any behavior change.
