PCI: Add pci_free_host_bridge() interface
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.
