v4 -> v5:
1. change the type of global variable and struct member named "non_strict" from

2. cancel the unnecessary parameter "strict" of __arm_lpae_unmap which was added
    in v4.
3. change boot option "arm_iommu" to "iommu.non_strict".
4. convert __iommu_dma_unmap to use iommu_unmap_fast()/iommu_tlb_sync(), because
    non-leaf unmaps still need to be synchronous.

Thanks for Robin's review comments.

Since this is 90% of the way there now, I suggest Robin picks up what's here
and incorporates his remaining review comments directly (especially since it
sounded like Zhen Lei hasn't got much free time lately). With that, I can
queue this lot via my smmu branch, which already has some stuff queued
for SMMUv3 and io-pgtable.

Please shout if you have any objections, but I'm keen for this not to
languish on the lists given how close it is!

Sure, having got this far I'd like to see it get done too. I'll make some time and give it a go.
