Make the memory wipe code handle 64 bit addresses properly
When telling the memory wipe infrastructure about regions it should and
shouldn't wipe, some of those addresses may be 64 bits on x86. This change
makes the infrastructure pass around those addresses intact instead of
truncating them, and then simply ignore the regions that are unaddressable
by U-Boot.
BUG=None
TEST=Built and booted on Lumpy. Built on Kaen
