Warner Losh 7964bd0c70 Reserve the DMA memory at attach time, rather than at use. While
reserving it at use time is more miserly, low memory (< 16MB)
evaporates quickly on many systems, so there may not be any suitable
buffers available.  This specifically doesn't use the newer, fancier
isa_dma_init to ease merging to 5.
