It turns out that there are no platforms that have PCI but don't have an MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing kernels for those platforms a lot, and avoids a lot of inadvertent build regressions. Add a dependency for CONFIG_PCI and remove all the ones for PCI specific device drivers that are currently marked not having it. There are a few platforms that have an optional MMU, but they usually cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is mainly for historic reasons, and anyone using those chips should really use the MMU these days.
