pci: Fix assigned-addresses for 64bit nonprefetchable BAR
975b31f80aff "pci: Put non-prefetchable 64bit BARs into 32bit MMIO window"
moved 64bit non-prefetchable BARs into 32bit non-prefetchable window
of a bridge. However the resource would still be advertised as 64bit
in the "assigned-addresses" property so fix the resource type.
