Abhi Singh 3c54570afc feat(io): add generic gpio spi bit-bang driver
When using a tpm breakout board with rpi3, we elected to bit-bang
gpio pins to emulate a spi interface, this implementation required a
driver to interface with the platform specific pins and emulate spi
functionality. The generic driver provides the ability to pass in a
gpio_spi_data structure that contains the necessary gpio pins in
order to simulate spi operations (get_access, start, stop, xfer).
