Modified Arduino libraries for Bluey from https://github.com/sandeepmistry/arduino-nRF5/ to add Software Serial support

What's different from the arduino-bluey repository?

• There is no Serial port for TX on the Bluey module other than the interface that connects to CP2104. This is because nRF52 supports only one UART peripheral.
• The developers at Bluey suggested that the only way you can use UART on custom pins is by disabling the UART on CP2104 pins 6 and 8 and configuring them to the pins of your choice in the Arduino pin mapping
• While working with this BLE module, found this to be a strong limitation since the single serial port was needed for debugging over the USB interface. Desperately needed another Serial port. Hence, started exploring the Software Serial options
• The software serial libarary did not work out of the box with the arduino libraries in https://github.com/electronut/arduino-bluey since there were further fixes in it's parent repository that did not reflect in this, so had to make some local changes from the nRF52 Arduino libraries.
