Log Message:
Add BUS_ADDR_{LO,HI}32() macros to correctly extract the lower and
upper halves of 64-bit DMA addresses for 32-bit and 64-bit bus_addr_t.
This is a common pattern in modern drivers, so it's a good idea to provide
a common correct definition.
This particular implementation suggested by riastradh@.
