hw/arm/smmu: Introduce smmu_configs_inv_sid_range() helper

Browse source 
Use a similar terminology smmu_hash_remove_by_sid_range() as the one
being used for other hash table matching functions since
smmuv3_invalidate_ste() name is not self explanatory, and introduce a
helper that invokes the g_hash_table_foreach_remove.

No functional change intended.
