This patch adds support the 2560x1600@90Hz dual DSI command mode panel by
EDO in combination with a Raydium RM69380 driver IC.

This driver IC can be found in the following devices:
 * Lenovo Xiaoxin Pad Pro 2021 (TB-J716F) with EDO panel
 * Lenovo Tab P11 Pro (TB-J706F) with EDO panel
 * Robo & Kala 2-in-1 Laptop with Sharp panel

Changes in v4:
- Fix up Kconfig
- Switch to devm_mipi_dsi_attach to benefit from automatic detaching
- Initialize panel at a lower brightness
- Dropped debug logs
- Signify second DSI interface in mipi_dsi_device_info as "RM69380 DSI1"
- Changed 'addtionalProperties' to 'unevaluatedProperties' in dt-binding
- Dropped 'ports' in dt-binding
- Link to v3: https://lore.kernel.org/r/20240416-raydium-rm69380-driver-v3-0-21600ac4ce5f@mainlining.org

- Fix error handling code in probe function
- Include video/mipi_display.h and make use of MIPI command definitions
- Removed DRM_MODE_TYPE_PREFERRED
- Dropped 'prepared' bool entirely
- Register second DSI host using mipi_dsi_device_register_full()
- Link to v2: https://lore.kernel.org/r/20240415-raydium-rm69380-driver-v2-0-524216461306@mainlining.org

Changes in v2:
