Christoph Hellwig 9739ab7eda powerpc: enable a 30-bit ZONE_DMA for 32-bit pmac
With the strict dma mask checking introduced with the switch to
the generic DMA direct code common wifi chips on 32-bit powerbooks
stopped working.  Add a 30-bit ZONE_DMA to the 32-bit pmac builds
to allow them to reliably allocate dma coherent memory.
