[PATCH 4/6] drm/msm/hdmi: make hdmi_phy_8960 OF clk provider

[Dmitry Baryshkov <dmitry.baryshkov@linaro.org>]

On MSM8960 the HDMI PHY provides the PLL clock to the MMCC. As we are
preparing to convert the MSM8960 to use DT clocks properties (rather
than global clock names), register the OF clock provider.
