arm64: dts: rockchip: Correct MIPI DPHY PLL clock on rk3399

There is a further gate in between the mipidphy reference clock and the
actual ref-clock input to the dsi host, making the clock hirarchy look like
clk_24m --> Gate11[14] --> clk_mipidphy_ref --> Gate21[0] --> clk_dphy_pll

Fix the clock reference so that the whole clock subtree gets enabled when
the dsi host needs it.
