arm64: dts: apalis-imx8x: add missed module-level devices

Add an initial support of following devices in toradex_5.4-2.1.x-imx:
- AD7879 touch controller
- ADC
- Audio subsystem and sgtl5000 codec
- Backlight
- DSI->HDMI adapter
- FlexCAN
- GPIO Fan
- GPIO WakeUp
- GPU
- MIPI-CSI
- MIPI-DSI
- On-module EEPROM
- PCAL GPIO expanders
- PCIeB
- USB/USB Hub
- VPU Encoder/Decoder
- etc.
