d/patches: renesas: Disable CMD_I2C config option

Currently, the u-boot binary is going beyond the 1MiB limit on R-Car Gen3. Upstream u-boot doesn't have this problem as the DISTRO_DEFAULTS config option is disabled.

Let's disable the CMD_I2C config option to shrink the final image size between the boundaries.

NOTE: Ideally, other unused options should be shrinked as well. In fact, if a feature is not supported nor used across all Apertis platforms, it could be globally disabled.
