In order to avoid unnecessary pollution of the global symbol namespace
move the core bma400 functions into a bma400 specific namespace
and import that into the two bus modules.

When an i2c or spi driver's remove function returns a non-zero error
code nothing happens apart from emitting a generic error message. Make
this error message more device specific and return zero instead in the
remove callbacks. As the return value of bma400_remove() is unused then,
change the function to not yield a return value.

Add a IIO driver for the Bosch BMA400 3-axes ultra-low power accelerometer.
The driver supports reading from the acceleration and temperature
registers. The driver also supports reading and configuring the output data
rate, oversampling ratio, and scale.
