Subject: [PATCH v2 4/4] drm/panel: ilitek-ili9806e: add Rocktech RK050HR345-CT106A SPI panel

Add support for the Rocktech RK050HR345-CT106A panel based on the
Ilitek ILI9806E controller using the SPI bus.

The driver is designed to be easily extensible to support other panels
with different initialization sequences and display timings by
providing a specific descriptor structure for each model.

Signed-off-by: Dario Binacchi <dario.binacchi@...rulasolutions.com>

---

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.
