	implementation of SWI UART change mode.
void	swi_uart_discover_buses (int swi_uart_buses[], int max_buses)
	discover UART buses available for this hardware this maintains a list of logical to physical bus mappings freeing the application of the a-priori knowledge
ATCA_STATUS	swi_uart_send_byte (ATCASWIMaster_t *instance, uint8_t data)
	HAL implementation of SWI UART send byte over ASF. This function send one byte over UART.
ATCA_STATUS	swi_uart_receive_byte (ATCASWIMaster_t *instance, uint8_t *data)
	HAL implementation of SWI UART receive bytes over ASF. This function receive one byte over UART.

Detailed Description
