[PATCHv2 3/3] arm64: Use arm64 coherent APIs for non-coherent freeing

[lauraa@codeaurora.org (Laura Abbott)]

The noncoherent free function currently unconditionally frees
back to the page allocator which is incorrect for CMA pages.
call the coherent free function to correctly differentiate
between pages.
