Identification of PMBus slaves and options configuration

Polling the connected slaves
After connecting the interface board, the GUI should poll the bus to identify the connected
slaves.
In the polling procedure the GUI scans the entire slave address range except 0x18 which is
the alert response address. As soon as the polling completes, the GUI lists the connected
slave addresses in the device selection window. The GUI can support four simultaneous
PMBus slaves.
