drm: adv7511: Add support for i2c_new_secondary_device

The ADV7511 has four 256-byte maps that can be accessed via the main I2C
ports. Each map has it own I2C address and acts as a standard slave
device on the I2C bus.

Allow a device tree node to override the default addresses so that
address conflicts with other devices on the same bus may be resolved at
the board description level.
