Subject[PATCH 6/9] PCI: consolidate PCI config entry in drivers/pci
Date
There is no good reason to duplicate the PCI menu in every architecture.
Instead provide a selectable HAVE_PCI symbol that indicates availability
of PCI support and the handle the rest in drivers/pci.

Note that for powerpc we now select HAVE_PCI globally instead of the
convoluted mess of conditional or or non-conditional support per board,
similar to what we do e.g. on x86. For alpha PCI is selected for the
non-jensen configs as it was the default before, and a lot of code does
not compile without PCI enabled. On other architectures with limited
PCI support that wasn't as complicated I've left the selection as-is.
