From: Arnd Bergmann <a...@arndb.de>

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.
