board: ge: mx53ppd: enable DM_VIDEO



Enable DM_VIDEO for mx53ppd.  This also requires DM_REGULATOR_FIXED and
DM_PWM for the backlight, and `failbootcmd' is changed to use lcdputs.

Remove unused MX53PPD_LCD_POWER.
Remove old (incorrect) setup_iomux_lcd.
Enable backlight via display enable handler.
Use cls command to initiate display in HW agnostic manner.
