MLK-22870 arm64: dts: add OCOTP clock 

Use the kexec command to restart the root cell Linux, and the system
will hang up in imx8mm_soc_uid(). The reason is that ocotp root clk is
not enabled when the unique ID is read. Therefore, add CLK_OCOTP_ROOT to
init-on-array in root.dts to ensure that ocotp root clk in the root cell
Linux is always enabled.
