[PATCH v4 1/4] PCI: Export pci_get_host_bridge_device() for use by pci-keystone

[Siddharth Vadapalli <s-vadapalli@ti.com>]

The pci-keystone.c driver uses the 'pci_get_host_bridge_device()' helper.
In preparation for enabling the pci-keystone.c driver to be built as a
loadable module, export 'pci_get_host_bridge_device()'.
