Changeset 59

Message:

Remove initial pre-driver-port code that configured the module via SPI with a network configuration to enable a ping test. Includes code to communicate via SPI and to read address/register/memory locations. Remove associated code credit for spi_transfer from playground. All these functions are now implemented within the driver itself. TODO: Could we implement the driver SPI comms in a more efficient manner?
