This patch moves dma resource allocation to a new function
alloc_dma_desc_resources, the reason for moving this to a new function
is to keep the memory allocations in a separate function. One more reason
it to get suspend and hibernation cases working without releasing and
allocating these resources during suspend-resume and freeze-restore
cases.
