mb/starlabs/starlite_adl: Add support for MXC6655 accelerometer

Browse source 
Add support for the Memsic MXC6655 accelerometer on I2C0, as an
alternative to the existing Kionix KCXJ9. Use the "detect" function
of the I2C generic driver to determine which is present at runtime.

TEST=build/boot starlite_adl with MXC6655, verify screen roation works
properly when detached from keyboard under Linux and Windows.
