Add support for Waveshare automatic recognition DSI panels which identify themselves at runtime via I2C registers. The driver reads screen type, rotation and refresh rate from registers 0xd0-0xd3 to select the appropriate display mode and DSI lane configuration. Supported configurations include 1200x1920 and 1920x1200 panels at both 30fps (2 lanes) and 60fps (4 lanes) refresh rates. Signed-off-by: Engineer_Will <646689853@qq.com>
Add the auto_rec overlay parameter to select the automatic recognition panel compatible string (waveshare,automatic-recognition-panel). This enables runtime panel detection via I2C for Waveshare DSI displays that support automatic identification. Use lowercase with underscores for the parameter name to follow kernel naming conventions. Signed-off-by: Engineer_Will <646689853@qq.com>

Add automatic panel recognition support for Waveshare DSI displays,targeting panels such as the 10.1inch DSI LCD (E) that identify themselves at runtime via I2C control registers.
