Subject: [PATCH 1/2] i2c: header: remove unneeded stuff regarding i2c_algorithm

The forward declaration is not needed anymore. The sentence about
"following structs" became obsolete when struct i2c_algorithm became a
kdoc. The paragraph about return values can go because we have this
information in kdoc already.
