overlays: colibri-imx8x: use mxsfb driver for LCD/VGA interfaces
This driver correctly supports display flags and fixes the pixel shift issue on displays with the data latching on the rising edge. The DPU-enabled driver for LCDIF device (display_lcdif) doesn't support display special flags. It prevents the VGA port on the Colibri Evaluation board working correctly. The driver mxsfb (adma_lcdif) works well with display flags, so that it should be used as a default driver for LCD panels and VGA monitors. Note, the mxsfb driver DOESN'T support imx dpu unit.
