dma-debug: don't enforce dma mapping check on noncoherent allocations
As discussed in [1], there is no need to enforce dma mapping check on
noncoherent allocations, a simple test on the returned CPU address is
good enough.
Add a new pair of debug helpers and use them for noncoherent alloc/free
to fix this issue.
Fixes: efa70f2fdc84 ("dma-mapping: add a new dma_alloc_pages API")
