[v2] hw/arm/smmu: Add invalidating function of config data

Commit Message

JianChunfu Feb. 21, 2025, 3:17 a.m. UTC

Uniform the removal judgement of g_hash_table_foreach_remove(), previous
name seems to perform the actual action while it just returns a Boolean.

v2: - move smmuv3_invalidate_ste() to smmu_hash_remove_by_sid_range()
    - add function smmu_configs_inv_sid_range()
v1: - Rename smmuv3_invalidate_ste to smmuv3_hash_remove_by_sid_range
