The PCI core's pci_scan_bridge_extend() contains convoluted logic specific
to setting up bus numbers for legacy CardBus bridges. Extract the CardBus
specific part out into setup-cardbus.c to make the core code cleaner and
allow omitting CardBus bridge support from modern systems.

Move CardBus window sizing parameters to setup-cardbus.c, which contains
all the other CardBus code.

PCI bridge window setup code includes special code to handle CardBus
bridges. CardBus has long since fallen out of favor and modern systems have
no use for it.
Move CardBus setup code to its own file and use existing CONFIG_CARDBUS to
decide whether it should be built or not.
