Migrate WFD to IOMMU APIs. Commit contains following changes: - Switch from allocate buffer model to use buffer model in order to have the flexibility to map buffers into seperate domains. - Use the ION caching APIs to flush buffers in case they are cached. Earlier on, we used uncached buffers, hence we didn't have a need to flush. Change-Id: I959027ee94a5d6074005f1de420c66cbe55db776 Signed-off-by: Deva Ramasubramanian <dramasub@codeaurora.org>
