clk: bind clk to new parent device
Clock re-parenting is not binding the clock's device to its new
parent device, it only calls the clock's ops->set_parent() API. The
changes in this commit re-parent the clock device to its new parent
so that subsequent operations like clk_get_parent() to point to the
proper parent.
