[PATCH] clk: fix a missing-free bug in clk_cpy_name()

[Gen Zhang]

In clk_cpy_name(), '*dst_p'('parent->name'and 'parent->fw_name') and 
'dst' are allcoted by kstrdup_const(). According to doc: "Strings 
allocated by kstrdup_const should be freed by kfree_const". So 
'parent->name', 'parent->fw_name' and 'dst' should be freed.
