Support for On Semiconductor RSL10 boards

[pbrandst]

There is at the moment unfortunately no support for the RSL10 boards from ON Semiconductor.
The RSL10 chip has an ARM Cortex M3 processor on chip and a Bluetooth stack and is a very low power component.
There exists some dev boards like the RSL10-SENSE-DB-GEVK which has some additional sensors. On Semiconductor provides a CMSIS package.
