Subject: [PATCH V3 08/15] clk: imx: add CLK_SET_RATE_PARENT for lcdif_pixel_src for i.MX7D

From: Peng Fan <peng.fan@....com>

Add flag 'CLK_SET_RATE_PARENT' to 'IMX7D_LCDIF_PIXEL_ROOT_SRC' to
propagate rate changes from LCDIF pixel clock to video PLL to
provide more accurate clock rate for LCDIF pixel clock.
