[RESEND PATCH] ARM: SAMSUNG: Add s3c_setparent_clksrc in s3c_set_clksrc

[jhbird . choi]

From: Jonghwan Choi <jhbird.choi@xxxxxxxxxxx>

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.
