PCI: versatile: Simplify host bridge window iteration

Browse Source 
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.

No functional change intended.
