The imx6sx clock driver harcodes PLL5 as the LCDIF1 parent, but in preparation for removing such hardcoding, describe the parent relationship via devicetree. There are some boards that may want to use a different parent for the LCDIF due to EMI reasons, for example. With this approch, the user can change the LCDIF parent in the board devicetree if needed.
