If buf unmap is executed without successful kernel unmap
the vmap counter mismatches. Check for error scenarios in
kernel unmap function and ignore buf unmap if not necessary.

While allocating and importing ION buffers, make sure to check
for probe complete flag before proceeding instead of checking for
the flag AND smmu_enabled flag. This way the restriction will be
centralized for either types of targets with and without SMMU.

Device pointer needs to be stored during probe of msm_audio_ion
platform driver so that the same can be used later for mapping
dma_buff allocated for different clients. Store device pointer
for both cases where SMMU may be present or absent on a particular
platform.

ION memory allocator is used for audio use cases even on targets
without SMMU. Add support for ION on those targets where ADSP
might not have an SMMU in front of it.

Update logic for pointer meant to hold virtual address of ION
buffers allocated, so that the pointer is available across
function boundary.

on dma_buf with CACHED Flag on.

Between Linux-4.9 and Linux-4.14, upstream has updated the
ION APIs significantly to make ION ready to bring out of
staging folder. This has changed the way ION and dma_buf
APIs used to work together for allocating, mapping and
deallocating ION buffers.
Update MSM Audio ION wrapper functions used by audio drivers
to reflect these ION API changes as per upstream ION.

Based on where the code is synced the driver should allow
both static and dynamic linked compilation.
Also remove __exit for modules loaded from another common
init/exit functions.
