Some update on the progress:
I figured out that I have switched SDA and SCL lines for the monitor
connection through HDMI. I have flipped that to proper position and I
can see additional devices on the bus:

root@beaglebone:~#
0x20 - I/O expander
0x61 - external DAC
0x68 - RTC clock
0x20, 0x37, 0x3a, 0x4a, 0x4b and 0x50 appear after I connect the monitor
ro hdmi connector.
I think I have figured out that I have to put i2c = <&i2c2>; in the
overlay file, as I think it reffers to the hardware number.
Now when I boot BeagleBone Black in the debug console I see:

There are some errors regarding reading data from TDA chip. When i
placed i2c1 in the tree overlay file it just said one line about hdmi
i2c problem.
Looking forward to your answer.
