pci: forward-declare bridge memory banks internally

The PCI bridge code maps the config, I/O, memory, and bridge banks
before their definitions later in pci.cpp. Clang requires declarations
before those uses.

Keep the declarations and definitions in an anonymous namespace. The
objects remain private to pci.cpp even though the forward declarations
use extern syntax.
