[Freedreno] [PATCH v3 2/7] dt-bindings: msm/mdp5: Document optional TBU and TBU_RT clocks

[kholk11 at gmail.com]

From: AngeloGioacchino Del Regno <kholk11 at gmail.com>

These two clocks aren't present in all versions of the MDP5 HW:
where present, they are needed to enable the Translation Buffer
Unit(s).
