Just an idea how to restructure this, you could have
config PCI_POSSIBLE
bool
help
select this from your platform if it can support PCI.
config PCI_DEFAULT
bool
select
help
select this from your platform if you want PCI on by default
config PCI
bool "PCI support"
depends on PCI_POSSIBLE || PCI_DEFAULT
default PCI_DEFAULT
config 40x
# there could be PCI, but normally there isn't
select PCI_POSSIBLE
config PPC_83xx
# PCI is normally wanted on 83xx, but you can disable it
select PCI_DEFAULT
config CHRP
# CHRP can only be built correctly when PCI is enabled
select PCI
