Include pci/pcie/Kconfig directly from pci/Kconfig, so arches don't
have to source both pci/Kconfig and pci/pcie/Kconfig.
Note that this effectively adds pci/pcie/Kconfig to the following
arches, because they already sourced drivers/pci/Kconfig but they
previously did not source drivers/pci/pcie/Kconfig:
alpha
avr32
blackfin
frv
m32r
m68k
microblaze
mn10300
parisc
sparc
unicore32
xtensa
