PCI: controller: PCI_IXP4XX should depend on ARCH_IXP4XX

The Intel IXP4xx PCI controller is only present on Intel IXP4xx
XScale-based network processor SoCs.

Add a dependency on ARCH_IXP4XX, to prevent asking the user about this
driver when configuring a kernel without support for the XScale
processor family.
