iommu/arm-smmu-v3: Perform per-domain invalidations using arm_smmu_invs

Browse source 
Replace the old invalidation functions with arm_smmu_domain_inv_range() in
all the existing invalidation routines. And deprecate the old functions.

The new arm_smmu_domain_inv_range() handles the CMDQ_MAX_TLBI_OPS as well,
so drop it in the SVA function.

Since arm_smmu_cmdq_batch_add_range() has only one caller now, and it must
be given a valid size, add a WARN_ON_ONCE to catch any missed case.

Also update the comments in arm_smmu_tlb_inv_context() to clarify things
with the new invalidation functions.
