/// ## Arguments
/// * `transfer_cfg` - Transfer configuration which includes configuration
/// which can change across individual SPI transfers like SPI mode or SPI clock.
/// If only one device is connected, this configuration only needs to be done
/// once.
/// * `spi` - SPI bus to use
/// * `pins` - Pins to be used for SPI transactions. These pins are consumed
/// to ensure the pins can not be used for other purposes anymore
/// * `spi_cfg` - Configuration specific to the SPI bus
/// * `transfer_cfg` - Optional initial transfer configuration which includes
/// configuration which can change across individual SPI transfers like SPI mode
/// or SPI clock. If only one device is connected, this configuration only needs
/// to be done once.
/// * `syscfg` - Can be passed optionally to enable the peripheral clock
