Changes for v5:
- Use 'interpolation-steps' to fill the brightness level table
- Remove not needed status = "okay" properties
- Replace goodix_ts -> touchscreen
- Replace sgtl5000 -> audio-codec

This patch depends on PWM backlight intepolation work:
https://patchwork.kernel.org/patch/10330775/
https://patchwork.kernel.org/patch/10330777/

Changes for v4:
- Remove not needed bus-format-override = "rgb565";
  property

Changes for v3:
- Provide proper compatible for RTC DTS node
- Remove wrong comment style for beeper
- Add proper SPDX entries for DTS files
- Add vendor prefix to a separate patch

Changes for v2:
- SPDX license identifiers used
- Separate regulators
- Proper beeper driver
- Use of the lcd panel (with compatible) instead of timings provided in
  device tree
- Add IRQ types (like IRQ_TYPE_EDGE_FALLING) and GPIO active levels (like
  GPIO_ACTIVE_HIGH)
- Remove not needed nodes
- Make W=1 dtbs compilation with no errors
