Hi Chris,

This adds a compatible string for the Allwinner Sun4i-A10 I2C controller. Without this, boards based on the R8 and A13 (at a minimum) fail to boot.

Applied to sunxi/master, thanks!
Out of curiosity, can you say what "fail to boot" means, exactly? I see that indeed i2c in U-Boot proper got lost when I2C was moved to DM in the v2022.01 merge window, but that didn't have any visible effect apart from the "i2c" command not working on my BananaPi. Ethernet, USB and Linux boot worked fine, still.
Cheers, Andre
