* Enable/disable the SPI slave select
* Enable/disable the SPI slave select. The implementation of this method
* must include handshaking: If a device is selected, it must hold off

*
* Input Parameters:
* selected: TRUE: slave selected, FALSE: slave de-selected
* dev - Device-specific state data
* devid - Identifies the device to select
* selected - TRUE: slave selected, FALSE: slave de-selected
*
* Returned Value:
* None
