[Zhen Lei]

Changelog:
v2 -> v3:
1. add support for pci device hotplug, which missed in patch v2.
2. only support #iommu-cells = <1>, add corresponding description in arm,smmu-v3.txt.
3. add function find_smmu_by_device which extracted from find_smmu_by_node, to resolve
   the problem mentioned by Robin Murphy in [PATCH v2 7/9].
   Additionally:
   +    platform_set_drvdata(pdev, smmu);       //Patch v2
   +	dev->archdata.iommu = smmu;             //Patch v3, dev = &pdev->dev

v1 -> v2:
update the implementation of patch 1/9 according to Will Deacon's suggestion.
update the comment of patch 3/9 and 4/9.
use arm_smmu_options to skip the execution of command CMD_PREFETCH_CONFIG, see patch 5/9.
