video: Add support for the ANX9804 parallel lcd to dp bridge chip
Add support for the ANX9804 bridge chip, which can take pixel data coming from a parallel LCD interface and translate it on the fly into a DP interface for driving eDP TFT displays. It uses I2C for configuration. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Anatolij Gustschin <agust@denx.de>
