clk: thead: Correct parent for DPU pixel clocks

The dpu0_pixelclk and dpu1_pixelclk gates were incorrectly parented to
the video_pll_clk.

According to the TH1520 TRM, the "dpu0_pixelclk" should be sourced from
"DPU0 PLL DIV CLK". In this driver, "DPU0 PLL DIV CLK" corresponds to
the `dpu0_clk` clock, which is a divider whose parent is the
`dpu0_pll_clk`.

This patch corrects the clock hierarchy by reparenting `dpu0_pixelclk`
to `dpu0_clk`. By symmetry, `dpu1_pixelclk` is also reparented to its
correct source, `dpu1_clk`.
