Subject: [PATCH v3 1/2] ARM: dts: rockchip: assigned-clock-parents to SCLK_HDMI_PHY for DCLK_VOP

If dclk_vop use CLK_SET_RATE_PARENT and CLK_SET_RATE_NO_REPARENT
we should assign clk parent in DT to make it extra clear
that hdmiphy should be used as dclk_vop parent.

Fixes: 1d34b9757523 ("clk: rockchip: Set parent rate for DCLK_VOP clock on RK3228")
