Zhen Lei d0e108b8e9 iommu/vt-d: Add support for IOMMU default DMA mode build options
Make IOMMU_DEFAULT_LAZY default for when INTEL_IOMMU config is set,
as is current behaviour.

Also delete global flag intel_iommu_strict:
- In intel_iommu_setup(), call iommu_set_dma_strict(true) directly. Also
  remove the print, as iommu_subsys_init() prints the mode and we have
  already marked this param as deprecated.

- For cap_caching_mode() check in intel_iommu_setup(), call
  iommu_set_dma_strict(true) directly; also reword the accompanying print
  with a level downgrade and also add the missing '\n'.

- For Ironlake GPU, again call iommu_set_dma_strict(true) directly and
  keep the accompanying print.
