arm64: dts: qcom: sc8180x: Add missing MDP clocks

The ROT clock is required for the MDP block to function (looks like some
others depend on it), and whike the LUT clock's purpose is not clear,
it's likely better to turn on all of MDP's dependencies rather than not
doing so.

Add these clocks under the MDP node. This also makes Primus work without
clk_ignore_unused (as far as the dmesg-visible errors go, anyway).
