Translated to devicetree

WIP At the we use a samsung display with same resolution and similar timings which works. But to optimize the devicetree someone has to decode EDID to panel-timings

GPIOs

Controlling the following GPIOs from UEFI Shell gave the result below. The GPIOs were extracted from ACPI

GPIO	Backlight	Logo	Note	Function
B2	Y	N	Image fades out	LVDS power down
DD0	N	Y	Logo can bee seen with external light source	backlight power
DD2	N	N	Display is dead	panel power
H0	N	Y	PWM brightness control	PWM brightness

Connector

Pin
2/3 Panel VDD	GPIO DD2
25 BL_PWM	GPIO H0
26 Backlight enable	GPIO DD0
28/29/30 LED Anode	Always connected to 12V
