clk: mediatek: mt6735-apmixedsys: Fix an error handling path in clk_mt6735_apmixed_probe()

If an error occurs after a successful mtk_alloc_clk_data(),
mtk_free_clk_data() should be called, as already done in the .remove()
function.

Switch to mtk_devm_alloc_clk_data() in order to fix the memory leak in the
probe function, and simplify the remove function.
