drm: bridge: vga-dac: Add adi,adv7123 compatible string
The ADV7123 is a transparent VGA DAC. Unlike dumb VGA DACs it can be controlled through a power save pin, and requires a power supply. However, on most boards where the device is used neither the power save signal nor the power supply are controllable. To avoid developing a separate device-specific driver add an "adi,adv7123" compatible entry to the dumb-vga-dac driver. This will allow supporting most ADV7123-based boards easily, while allowing future development of an adv7123 driver when needed without breaking backward compatibility.
