dt: Fix touchscreen
For some reason, the ecspi SS1 line appears on the output when selecting GPIO in the pinmux. Also, the x-axis is inverted, and pressure values upon press hover around 250.

* Backlight (configured active by bootloader for now)

* Notification LEDs (not populated on HW anyways)
|

* Broken
|

* Touchscreen does report any events
|
||||
* Touchscreen mapping is off (offset and skewed), prossibly fixable in libinput via transformation matrix.

* Speaker-amp (gpiochip4,2) not turned on automatically (needs to be activated using gpioset for now)
