RFC --> v1
1. Resend the patches for ECMDQ preparation and remove the patches for ECMDQ implementation.
2. Patch 2 is modified. Other patches remain unchanged.
   1) Add static helper __arm_smmu_cmdq_issue_cmd(), and make arm_smmu_cmdq_issue_cmd()
      and arm_smmu_cmdq_issue_cmd_with_sync() implement based on it.
   2) Remove unused arm_smmu_cmdq_issue_sync().
