The ARM SMMU driver might get built with CONFIG_PCI disabled. It would thus have to wrap any use of ATS helpers around #ifdef CONFIG_PCI, which isn't ideal. A nicer solution is to always define these helpers. Since CONFIG_PCI_ATS is only enabled in association with CONFIG_PCI, move defines outside of CONFIG_PCI to prevent build failure when PCI is disabled.
