Add missing "avdd-0v9-supply" and "avdd-1v8-supply" properties to the "hdmi" node in the Pine64 RockPro64 board dtsi file. To achieve this, also add the associated "vcca_0v9" regulator that produces the 0.9 V supply, [1][2] which hasn't been defined previously in the board dtsi file. This also eliminates the following warnings from the kernel log: dwhdmi-rockchip ff940000.hdmi: supply avdd-0v9 not found, using dummy regulator dwhdmi-rockchip ff940000.hdmi: supply avdd-1v8 not found, using dummy regulator There are no functional changes to the way board works with these additions, because the "vcc1v8_dvp" and "vcca_0v9" regulators are always enabled, [1][2] but these additions improve the accuracy of hardware description. These changes apply to the both supported hardware revisions of the Pine64 RockPro64, i.e. to the production-run revisions 2.0 and 2.1.
