clk: imx: imx8qxp: Fix elcdif_pll clock

Move the elcdif_pll clock initialization before the lcd_clk, since the
elcdif_clk needs to be initialized ahead of lcd_clk, being its parent.
This change fixes issues with the LCD clocks during suspend/resume.

Fixes: babfaa9556d7 ("clk: imx: scu: add more scu clocks")
