v0.4.0 is missing embedded_hal_0_2::blocking::i2c traits?

This breaks when moving from 0.3.2 to [0.4.0-alpha.1](https://github.com/rust-embedded/linux-embedded-hal/compare/v0.3.0...v0.4.0-alpha.1) -- but the changelog does not mention this?

Start by comparing the embedded-hal implementations in v0.3.2 and v0.4.0-alpha.1, then inspect examples/basic.rs and the reported trait bounds in the consumer code. Done means the I2cdev type satisfies the required embedded_hal_0_2 blocking I2C traits or the compatibility change is clearly documented.
