Subject: [PATCH 2/4] PCI: Move resource reassignment func declarations into pci/pci.h

Neither pci_reassign_bridge_resources() nor pci_reassign_resource() is
used outside of the PCI subsystem. They seem to be naturally static
functions but since resource fitting/assignment is split between
setup-bus.c and setup-res.c, they fall into different sides of the
divide and need to be declared).

Move the declarations of pci_reassign_bridge_resources() and
pci_reassign_resource() into pci/pci.h to keep them internal to PCI
subsystem.
