For DMA pool scenario the plugged in allocation ops are not
used for carveout allocation. It is necessary to call a differnt
function that does not zero the DMA pool memory gotten from
the call to dma_alloc_coherent.
Call the dma_malloc_coherent (non-zeroing) api in the case
of late attach to guarantee that the memory is not zero-ed for
either a CMA or DMA pool. The memory for virtio rings is not
used in U-Boot, so need not use the non-zeroing function.
