Looks like on my board codec sits at address 0x10, and according to
schematics that's what its address is supposed to be.

See http://files.pine64.org/doc/rockpro64/rockpro64_v21-SCH.pdf

Codec address is selected by pin CE of ES8316, and on rockpro64 it
goes to GND through R226. So address should be 0x10.
