[PATCH 1/2] dt-bindings: display: rockchip, inno-hdmi: Fix ref clk Document of RK3036 compatible

[Andy Yan]

From: Andy Yan <andy....@rock-chips.com>

The RK3036 HDMI DDC bus requires it's PHY's reference clock to be enabled
first before normal DDC communication can be carried out.

Therefore, both RK3036 and RK3128 HDMI require two identical clocks.
