From: Jonghwan Choi <jhbird.choi@samsung.com>
Currently we have to run clk_set_parent to change clock source. But if there are sources & parent defined, it means we will select a parent in multiple clock sources. So sources & parent are already defined, set the parent clock int s3c_set_clksrc. Then we can reduce many clk_set_parent function in driver or setup_clock function.
