 hdmi_phy_configure_dwc_hdmi_3d_tx

Ignore this patch, Jose has a better patch to solve rk3399 hdmi phy 
configure.

Hi Jose

Sorry for missing your patch about hdmi 2.0 vendor phy fixup: 
https://patchwork.kernel.org/patch/9702229
It works fine on rk3399/rk3288, can you resend a standard patch to upstream?

Thanks
