config.mk is updated to provide this file to boards through the built-in mechanism:

This is slightly out-of-date now; in next-20120118, that node's compatible flag is nvidia,tegra20-i2c-dvc. The HW register layout is somewhat different for this I2C controller, and the different compatible flag is how the driver this.

Still, you can always apply that fix in a later patch before you add I2C support.
