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.
Include the osc_32k clock in SPL DTs as a low risk fix for v2025.01 release.
This way, fdtdec_parse_phandle_with_args() can resolve both the osc_32k and
following osc_24m phandle and successfully look up the osc_24m clock.
