This series extends the Ilitek ILI9806E panel driver to support the
Rocktech RK050HR345-CT106A model via SPI.

To achieve this, the current driver (previously restricted to DSI) is
refactored to support both DSI and SPI variants independently.

The series includes:
 - A refactoring of the existing driver and Kconfig to support
   multiple buses.
 - DT binding documentation for the Rocktech RK050HR345-CT106A.
 - The implementation of the SPI-based driver for the Rocktech panel.

Changes in v4:
- Fix "WARNING: unmet direct dependencies detected for
  DRM_PANEL_ILITEK_ILI9806E_CORE" reported by kernel test robot

Changes in v3:
- Add Reviewed-by tag of Rob Herring

Changes in v2:
- Introduce DRM_PANEL_ILITEK_ILI9806E_CORE hidden kconfig option.
- Split core and DSI logic.
- Restore vdd-supply as required for both DSI and SPI types in the
  dt-bindings.
- Dop useless settings in case of rocktech,rk050hr345-ct106a in the
  dt-bindings.
