iommu/arm-smmu-v3: Align invalid range with leaf page size upwards when support RIL

virt inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I401IF


CVE: NA

------------------------------

In the __arm_smmu_tlb_inv_range(), the fileds of TLBI CMD is
calculated based on the invalid range and the leaf page size,
when SMMU supports RIL. It will cause some errors when the
invalid range isn't aligned with the leaf page size.

1. The num_pages will be zero, if the invalid range is less
than b. Then it will enter an endless loop in
__arm_smmu_tlb_inv_range().
2. The actual invalid range will only be part of the invalid
range. If the invalid range is not an integral multiple of
the leaf page size.

To align invalid range with leaf page size upwards will solve
the two issues.
