clk: s5pv210: add missing call to samsung_clk_of_add_provider()

commit ba30011577330b7e29ecb5916d89c6db9fbc5b3d upstream.

Commit d5e136a21b2028fb1f45143ea7112d5869bfc6c7 ("clk: samsung: Register
clk provider only after registering its all clocks", merged to v3.17-rc1)
modified a way that driver registers registers to core framework. This
change has not been applied to s5pv210 clocks driver, which has been
merged in parallel to that commit. This patch adds a missing call to
samsung_clk_of_add_provider(), so the driver is operational again.
