PCI: consolidate the PCI_DOMAINS and PCI_DOMAINS_GENERIC config options 

Move the definitions to drivers/pci and let the architectures select
them.  Two small differences to before: PCI_DOMAINS_GENERIC now selects
PCI_DOMAINS, cutting down the churn for modern architectures.  As the
only architectured arm did previously also offer PCI_DOMAINS as a user
visible choice in addition to selecting it from the relevant configs,
this is gone now.

Enable PCI domains kernel management. Say Y if your machine
has a PCI bus hierarchy that requires more than one PCI
domain (aka segment) to be correctly managed. Say N otherwise.
If you don't know what to do here, say N.
