Since 50cdd3f74af3 ("clk: imx: clk-imx8mn Fix nand and spi clock parent"), drivers/clk/imx/clk-imx8mn.c clk_get_by_name(dev, "osc_24m", &osc_24m_clk) fails with error -22 EINVAL in SPL. This is because clk_get_by_name() in the end calls fdtdec_parse_phandle_with_args(), which iterates over all phandles in clock-controller@30380000 { clocks = <&osc_32k>, <&osc_24m>, ... } node 'clocks' property in an attempt to find the "osc_24m" clock, but fails to resolve the &osc_32k phandle and returns with -EINVAL.
Remove the clocks property phandles which cannot be resolved because their matching nodes are removed from SPL DTs, so fdtdec_parse_phandle_with_args() can resolve all the remaining valid nodes and successfully look up the osc_24m clock.
