This patch adds fix to update cached node to leaf node when there are no
iova free range left, which avoids unnecessary long iterations.

Introduce smmu_alloc_coherent and smmu_free_coherent functions to
allocate/free dma coherent memory from NUMA node associated with SMMU.
Replace all calls of dmam_alloc_coherent with smmu_alloc_coherent
for SMMU stream tables and command queues.
