It is just due to their very nature they tend to be placed under arch/, although there are some cases where the same system controller can be used for a range of processors (e.g. some Marvell chips can be used either with MIPS or PowerPC CPUs) and they might be arguably put in a place more suitable for sharing between architectures. See arch/mips/pci/ for an example of a generous bunch of PCI host drivers.
