clk: Add missing of_clk_set_defaults export

The of_clk_set_defaults() function is used in subsystems which can
be built as module. Add the missing symbol export entry so there
is no build errors like:
"ERROR: "of_clk_set_defaults" [drivers/i2c/i2c-core.ko] undefined!".

Fixes commit: 86be408bfbd846fab3c4ac21d6f9298bd2e4b790
