Subject: [PATCH v3.1 1/3] drm/rockchip: dw_hdmi: add RK3399 HDMI support
RK3399 and RK3288 shared the same HDMI IP controller, only some light
difference with GRF configure.

Changes in v3.1:
Correct documentation compatible's format(Rob Herring).
Changes in v3:
remove hdmi_phy_configure_dwc_hdmi_3d_tx callbak.
Changes in v2:
reuse hdmi_phy_configure_dwc_hdmi_3d_tx for phy configure
