ARM: dts: qcom: Update bw table and iommu properties on msm8937 GPU 

Following changes are made:

1. Update gpu_bw_tbl in terms of operating point for gpubw.
2. GPU takes care of creating desired dma mapping by itself,
   so disable iommu-dma.
3. Remove unsupported properties "qcom,protect" and
   "qcom,micro-mmu-control".
