[PATCH 7.2.y] iommu/arm-smmu-v3: Disable implementations during devm teardown

[Sasha Levin]

> Patch itself looks good to me for v7.2 stable and v6.8 longterm.

Queued for 6.18, thanks.

> But v6.12 longterm might need some extra fix, Sasha?

It does, but a different one. 6.12 has the devm teardown conversion and never
got 9ff145a25c5c ("iommu/tegra241-cmdqv: Fix CMD_SYNC use-after-free on
teardown") at all, so what it is missing is that commit rather than this
ordering fixup. It does not apply to 6.12 as-is either, because the
tegra241_cmdqv_destroy_vintf_user() hunk has no counterpart there.

Could one of you send an adapted 6.12.y version with that hunk dropped?
