PCI: altera: Simplify host bridge window iteration
The switch is the only statement in the resource_list_for_each_entry()
loop, so remove unnecessary "continue" statements in the switch. Simplify
checking for the required non-prefetchable memory aperture. Inline
altera_pcie_release_of_pci_ranges(), which is only called once.
No functional change intended.
