The BMI088, BMI085 and BMI090L accelerometer also support
I2C protocol, so let's add the missing I2C support.
The I2C interface of the {BMI085,BMI088,BMI090L} is compatible with
the I2C Specification UM10204 Rev. 03 (19 June 2007), available at
http://www.nxp.com. The {BMI085,BMI088,BMI090L} supports I2C standard
mode and fast mode, only 7-bit address mode is supported.
