Similarly, use devm_clk_get_optional_enabled() helper for cec clock, which additionally allows to remove the -ENOENT test. Moreover, the clock related members of struct dw_hdmi are not required anymore, hence drop them.

This is part of the internal dw_hdmi_synopsys_phy_ops struct, managed within dw_hdmi_detect_phy(). To handle vendor PHYs, DW HDMI driver doesn't make use of the internal PHY ops and, instead, relies on the glue layer to provide the phy_ops and phy_name members of struct dw_hdmi_plat_data. Drop the unnecessary assignments of DW internal PHY related members from structs rk3228_hdmi_drv_data and rk3328_hdmi_drv_data, since both set the phy_force_vendor flag and correctly provide the expected vendor PHY data.

HDMI 2.1 Quad-Pixel (QP) TX controller IP and a HDMI/eDP TX Combo PHY based on a Samsung IP block. Add just the basic support for now, i.e. RGB output up to 4K@60Hz, without audio, CEC or any of the HDMI 2.1 specific features.
