bma220: Initial implementation

This driver was developed based on the DFRobot Triple Axis
accelerometer BMA220 (Tiny):

http://www.dfrobot.com/index.php?route=product/product&product_id=1085

This device can only run at 3.3v DC.  Do not connect to 5v.

Added a private function definition for the installISR function. Done because C++
wasn't able to find the function definition for the java bindings.
