dsp: use dma handle as default input in hab export 



currently in hab driver, it want to hold all bufs as dmabuf for fulture implement, 
and it's hard to get dmabuf fd/handle from a kva, so hab need to generate a new
dmabuf for itself, and this will intruduce audio crash issue
in conclusion, for now hab just accept dma fd/handl as input in KHAB export path.
