arm64: dts: imx8mp-kontron: Fix GPIO for display power switch

The GPIO that controls the power supply for the LVDS display
connector has changed between early prototypes and the current
production design of the hardware. Reflect this change in the
devicetree to properly switch on the panel supply.

This was working before even with the wrong GPIO due to the
bidirectional level shifter used on the board which drives the EN
signal high even when the input has a (weak) pull down configured as
reset condition of the SoC pad. As a result the display was working
but the supply was always on.

Tested on BL i.MX8MP to show the correct voltage level on the level
shifter input.
