[PATCH v1 21/25] PCI: rcar: Simplify host bridge window iteration

[Bjorn Helgaas]

The switch is the only statement in the resource_list_for_each_entry()
loop, so remove unnecessary cases and "continue" statements in the switch.
Inline rcar_pcie_release_of_pci_ranges(), which is only called once.

No functional change intended.
