[PATCH 1/1] arm64: dts: imx8mp: reparent MEDIA_MIPI_PHY1_REF to CLK_24M

This is already done in dsi node, introduced in commit eda09fe149df4
("arm64: dts: imx8mp: Add display pipeline components").
This needs to be applied to csi nodes as well or the clock might be busy
if both csi and dsi nodes are enabled.
Fixes error:
 clk: failed to reparent media_mipi_phy1_ref to osc_24m: -16
