MLK-17650-1 drm/bridge: adv7511: Add support for programmable i2c addresses
The DSI-HDMI converter, ADV7535, driver uses four i2c memory maps: MAIN,
DSI-CEC, EDID and PACKET.
While the MAIN address is hard-coded in the ROM chip, the other three
can be programmed into the MAIN memory map.
Currently, the three memory maps addresses, that can be programmed, are
hard-coded into the code.
In order to avoid conflicts with other i2c clients on the bus, update
the driver to use configurable addresses specified in DTS file.
