[PATCH v9 3/5] drm/rockchip: inno_hdmi: reorder clk_disable_unprepare call in unbind

From: Jeffy Chen <jeffy.chen at rock-chips.com>

In bind the clk_prepare_enable of the HDMI pclk is called before adding the
i2c_adapter. So it should be the other way around in unbind, first remove
the i2c_adapter and then call the clk_disable_unprepare.
