I tested !CONFIG_IS_ENABLED(DM_I2C) alone, but the mezzanine SPL still
fails to link because SPL_DM_I2C is enabled while SPL_I2C is not.

Checking both works:

if (!(CONFIG_IS_ENABLED(I2C) && CONFIG_IS_ENABLED(DM_I2C)))
    return false;

I tested the mezzanine build successfully with this change.

I'll use this in v5 unless you see an issue.

Thanks,
