There are boards that only use hdmi1 such as ROCK 5 ITX. So there are two
choices for this board:

1, Enable hdptxphy0 as dependency of vop although it is not really used.

2, Overwrite vop node at board dts to make it only use hdptxphy1 like:

&vop {
	clocks = <&cru ACLK_VOP>,
		 <&cru HCLK_VOP>,
		 <&cru DCLK_VOP0>,
		 <&cru DCLK_VOP1>,
		 <&cru DCLK_VOP2>,
		 <&cru DCLK_VOP3>,
		 <&cru PCLK_VOP_ROOT>,
		 <&hdptxphy1>;
	clock-names = "aclk",
		      "hclk",
		      "dclk_vp0",
		      "dclk_vp1",
		      "dclk_vp2",
		      "dclk_vp3",
		      "pclk_vop",
		      "pll_hdmiphy1";
};

What do you think of these two method?
