zephyr: Add BMA255 emulator
Add BMA255 emulator which is emulated device on i2c bus. Emulated
accelerometer properties are defined through device tree, but they can
be changed in runtime through BMA255 emulator API. It allows to set
custom handlers for write and read messages to emulate more complex
scenarios or malfunctioning device.
