video: hx8394: Add panel driver for hannstar,hsd060bhw4
The driver is for panels based on the Himax HX8394 controller, such as the HannStar HSD060BHW4 720x1440 TFT LCD panel that uses a MIPI-DSI interface. This panel is used in Pinephone Pro. Signed-off-by: Ondrej Jirman <megi@xff.cz> Cc: Anatolij Gustschin <agust@denx.de>
