radeon/ttm/dma: Enable the TTM DMA pool if the device can only do 32-bit.
.. with the exception that we do not handle the AGP case. We only
deal with PCIe cards such as ATI ES1000 or HD3200 that have been
detected to only do DMA up to 32-bits.
Note: If the ttm.no_dma is set, this operation will not override
the TTM page pool to use the DMA one.
