clk: imx: clk-imx8mp: Allow media_disp pixel clock reconfigure parent rate

The media_disp[12]_pix clock supply LCDIFv3 pixel clock output. These
clocks are usually the only downstream clock from Video PLL on i.MX8MP.
Allow these clocks to reconfigure the Video PLL, as that results in
accurate pixel clock. If the Video PLL is not reconfigured, the pixel
clock accuracy is low.
