hw/arm/smmuv3: Introduce smmuv3_s1_range_inval() helper
Let's introduce an helper for S1 IOVA range invalidation.
This will be used for NH_VA and NH_VAA commands. It decodes
the same fields, trace, calls the UNMAP notifiers and
invalidate the corresponding IOTLB entries.
At the moment, we do not support 3.2 range invalidation yet.
So it reduces to a single IOVA invalidation.
Note the leaf bit now is also decoded for the CMD_TLBI_NH_VAA
command. At the moment it is only used for tracing.
