Log message:
Add a new page freelist, to which memory suitable for 32-bit dma on
xbridge(4) is assigned. Then, make bus_dmamem_alloc() allocate from this
range only.
This is transparent on O2, and makes sure the bus_dma memory address
will fit in the 2GB direct map of xbridge(4) chips - this is necessary for
PCI devices which do not handle 64 bit dma addresses.
