Add bindings for the same.

  * Major change in this patch -
    Changed compatible string from 'qcom,msm8996-smmu-v2' to
    'qcom,smmu-v2' to reflect the IP version rather than the
    platform on which it is used.
The bugs and how things are connected are all the same? I'd suggest you
keep both strings.

    compatible = "qcom,msm8996-smmu-v2", "qcom,smmu-v2";

    The same IP is used across multiple platforms including msm8996,
    and sdm845 etc.
But for only 2 or so platforms a fallback is not really worth it. You'll
probably be on SMMUv3 before too long...
Right. There's msm8998 as well, but as you said keeping both strings
will make more sense.
