Commit a52d1443bba1 ("PCI: Export host bridge registration interface")
exported the pci_alloc_host_bridge() interface so that PCI host
controllers drivers can make use of it.
Introduce pci_alloc_host_bridge() kernel counterpart to free the
host bridge data structures, pci_free_host_bridge(), export it
and update kernel functions releasing host bridge objects allocated
memory to make use of it.
