Subject: [PATCH v6 17/35] i2c: tegra: Remove likely/unlikely from the code

The likely/unlikely annotations should be used only in a hot paths of
performance-critical code. The I2C driver doesn't have such paths, and
thus, there is no justification for usage of likely/unlikely annotations
in the code. Hence remove them.
