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.

DMA buffer does not unmap after kernel ion map failure. It leads
to unexpected vaddr and memory leak.

physical memory through hypervisor abstracted ion layer,
which can be shared between APPS and ADSP directly.
