Thank you all for the feedback! I agree that enabling I2C_K1 by
default makes sense for the user experience.

To keep this patchset focused and avoid cross-subsystem complexity,
I'll send the I2C default configuration change as a separate patch to
the I2C maintainers after this series lands.

This way we can get the SD card support merged without delays while
still solving the dependency issue properly.
