clk: pass parent_rate into .set_rate
For most of .set_rate implementation, parent_rate will be used, so just like passing parent_rate into .recalc_rate, let's pass parent_rate into .set_rate too. It also updates the kernel doc for .set_rate ops. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Mike Turquette <mturquette@linaro.org>
