[PATCH 04/32] clk: mediatek: mt8135: fix memory leak on module removal

clk_mt8135_apmixed_probe() in clk-mt8135-apmixedsys.c does not call
platform_set_drvdata(), but clk_mt8135_apmixed_remove() callback calls
platform_get_drvdata().
This results in platform_get_drvdata() returning NULL,
which leads to calling kfree(NULL) in mtk_free_clk_data(NULL).
This leaves clk_data unreleased, causing a memory leak.

Fix this by calling platform_set_drvdata() during probe.
