Subject: [PATCH 13/13] arm64: dts: imx8mp: remove assigned-clock-rate of
 IMX8MP_VIDEO_PLL1

From: Benjamin Bara <benjamin.bara@...data.com>

Similar to commit 16c984524862 ("arm64: dts: imx8mp: don't initialize
audio clocks from CCM node").

With commit b09c68dc57c9 ("clk: imx: pll14xx: Support dynamic rates") in
place, the clock consumer (e.g. a panel) is able to set a more suitable
rate for the IMX8MP_VIDEO_PLL1. As composite-8m is now able to propagate
the rate through, avoid setting a rate in the dtsi.
