 Of course it does require them.  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.
