Add support for the Anbernic RG28XX display panel, as used in the RG28XX handheld gaming device from Anbernic. The panel is connected via an RGB parallel interface for image transmission and an SPI interface for configuration. Since the current panel driver for the ST7701 variants only supports MIPI DSI as an interface for configuration, add support for SPI as well.
