Add a sample application that allows a Zephyr-based Bluetooth controller to interface with an HCI driver via SPI. This sample implements the same BT SPI protocol already as Zephyr's HCI SPI driver. Currently, the sample only supports the legacy SPI API. Provide a single configuration file, avoiding board-specific files. Some board-specific configuration information must be provided via other means: - CONFIG_BT_CONTROLLER_TO_HOST_SPI_DEV_NAME - CONFIG_BT_CONTROLLER_TO_HOST_SPI_IRQ_DEV_NAME - CONFIG_BT_CONTROLLER_TO_HOST_SPI_IRQ_PIN Signed-off-by: Ricardo Salveti <ricardo.salveti@linaro.org> Signed-off-by: Marti Bolivar <marti.bolivar@linaro.org> Signed-off-by: Michael Scott <michael.scott@linaro.org>
