Modified Files:
        src/sys/arch/arm/arm32: pmap.c

Log Message:
In pmap_devmap_find_pa(), use 64-bit arithmetic to handle the case where
'pa + size' == 0x0. As in, if we're passed details of a region right at
the top of physical address space.

Otherwise we'll likely hit a false-positive due to 32-bit wrap-around.
