This is because Mediatek clock driver would be built as kernel module,
so clk_register_composite() used should be exported, then we could use
it. 

Please refer:
[PATCH 2/2] clk: mediatek: Add EXPORT_SYMBOL for kernel module support 
https://lkml.org/lkml/2020/7/1/124
+EXPORT_SYMBOL(mtk_clk_register_composites);

clk_register_composite() is used by Mediatek clk kernel module.
From export symbol: mtk_clk_register_composites.
