video: rockchip: mpp: iep2: remove reduce_req function

Browse Source 
1. Because of hw problems before, there will be problems with
high-frequency reset. So the frequency must be reduced before reset.
But this operation is unnecessary for now.
2. Iep share clk with rga on rk356x, so frequency reduction may affect rga.
